Schritt 1 - SchülerInnen vorbereiten
Schritt 2 - Die Messung In Gruppen von zwei SchülerInnen teilen sich ein Computer für die WZH Messung. Eine Gruppe bearbeitet 100 Events: Gruppe 1 - Events 1-100, Gruppe 2 - Events 101-200, usw. Die Events sind in Spy-online zu finden. SchülerInnen finden W+, W-, Z, und H Kandidaten und tragen die Resultate in eine Tabelle oder ein Zählblatt ein (zu finden unter). Wenn ein Z-Kandidat oder ein Higgs-Kandidat gefunden wurde, soll in die Tabelle eine Masse in GeV eingetragen werden. Die Massen sind auch am Zählblatt gedruckt. Für die Zahlen der W+ und W- Kandidaten, legen die SchülerInnen kleine Gewichte für jedes W+ (W-) in die W+ (W-) Schlüssel. Für jeden Z- oder H-Kandidat, befestigen die SchülerInnen eine Haftnotiz an die Massegrafik (2 GeV Intervalle). Die Massegrafik kann an der Wand oder einem Fenster angebracht sein. Hinweis: Benutzen Sie die "Offline-Option" wenn die Anzahl der SchülerInnen nicht groß ist. Das ist besser für das direkte Verständnis der Messung. |
Die "W-Waage" - 1 bonbon ist für 1 W+ oder W-. |
Die Massengrafik an der Wand wird machten auf Haftnotizen. |
Schritt 3 - Diskussion Die Waage benutzen Sie für die W+/W- Messung. Fragen:
Die Massegafik wird Peaks für J/Psi, Upsilon, und Z beinhalten. Helfen Sie den SchülerInnen diese zu erkennen. Gibt es einen Mini-Peak für das Higgs? Diskussionsthemen:

CMS WZH Measurement
- Description
- Requirements for hardware and software
- Outline of the day
- Student procedure
- Presentation of results
- Sample questions
- Moderators
- Material for students and teachers
- Students use event display of (mostly) leptonic decays to determine
- lepton ID (electron, muon),
- likely particle ID (W, Z, zoo, Higgs),
- charge if W, using curvature of electron or muon tracks,
- and masses if Z or Higgs candidates (taken from spreadsheet).
- Students use particle counts to find e/µ and W+/W- ratios.
- Students create mass plots. They find the mass of the Z boson and a possible Higgs signal but also other peaks in the mass plot to reveal additional particles.
- Students use the iSpy-online event display (or iSpy-dvd if there is insufficient internet bandwidth) and a Google online spreadsheet. Instructional screencasts are available for iSpy-online and iSpy-dvd (on DVD).
Requirements
for hardware and software
Online:
- Reliable, high-speed internet connection
- Up-to-date version of Firefox, Chrome, or Safari
- Masterclass DVD 2014
- Firefox 6.0 or higher only
- Spreadsheet (e.g. MS Excel)
- Work out a system for data transfer from student level to institute level and then for transmission of results to moderators
- Note: Moderators cannot show institute mass plot results in the videoconference. The mentor should share the institute mass plot through shared desktop. (In the Fermilab-based masterclass, there is an Indico page for the videoconference and the mentor can upload material such as a mass plot by means of a modification key.)
Outline of the day
- Arrival/Registration (~30 min)
- Cloud chamber, e/m apparatus, or other "gateway experience" apparatus setup for students to inspect
- Start and Ice-breaker activity (~30 min)
- Students in small groups create 1-2 good questions about particle physics and/or LHC. Where practical, groups should be made of students from different schools.
- Mentor presentation
- Template (~60 min, including Q&A)
- Tour of facilities/labs/cool stuff (~45 min)
- Analysis preparation (1-2 teachers facilitate; ~60 min, including Q&A)
- Presentation

- ATLAS data analysis slides (beta)
- Guided practice with discussion
- Lunch with a physicist (~60 min)
- Data Analysis (~90 min)
- Pre-conference (~30 min)
- Students and mentor discuss meaning of analysis results.
- Students and mentor discuss questions for other institutes.
- Revisit questions from ice-breaker, discuss which to ask in video conference.
- Designated IT expert preps video connection.
- Videoconference (~30 min)
- Greetings
- Presentation of results
- Discussion of results
- Q&A
- Summing up and evaluation (~15 min)
- Each pair of students analyzes a set of 100 events
- For each event, distinguish between electron and muon decay and between W+, W-, Z candidate, Higgs candidate, and zoo.
- Record into Google spreadsheet
- Be prepared to discuss in Masterclass Institute and in videoconference; prepare good questions.
Student procedure
- Pairs of students are assigned sets of 100 events to analyze in iSpy-online or iSpy-dvd.
- Event sets are found in the event display (http://www.i2u2.org/elab/cms/event-display) by choosing the folder icon (top left).
- A window appears. On the right side, students first choose "masterclass-2014" and then their event set (labelled masterclass_1, masterclass_2, etc.).
- Students also open the Google spreadsheet for their masterclass, find the tab for their Institute, and then scroll down to the area dedicated to their event set (also labelled masterclass_1, masterclass_2, etc.).
- Note: All institutes are strongly encouraged to use the provided Google spreadsheet rather than a local spreadsheet. The Google spreadsheet provided online is designed to facilitate transfer of results from students to mentors to moderators near-automatically. These are linked at the CMS Library page (scroll down to Data Analysis).


- Lepton ID (electron, muon). This is to characterize the event, not a individual particles.
- If the event has one muon track (long, red) or two muon tracks (actually likely a muon-antimuon pair) it is a single muon event.
- If the event has one electron track (short, red) or two electron track (actually likely an electron-positron pair) is is a single electron event.
- Likely particle ID (W, Z, zoo, Higgs)
- W candidate appears as a single electron track or muon track and a missing Et vector (yellow arrow, always transverse to beamline)
- Z candidate appears as 2 muons or 2 electrons; it is not always a Z. It may or may not have missing Et in the event.
- Suspected Higgs (H); these are rare but noteworthy. Events show as
- H→ZZ: 2 electrons and 2 muons, or 4 electrons, or 4 muons.
- H→γγ: no electron tracks but 2 large energy deposits (seen as towers) in ECal.
- Zoo events are "none of the above" but there can be interesting events among these.
- Charge if W, using curvature of electron or muon tracks (it helps to zoom in and to use a paper straight edge)
- Mass if Z or H candidate (taken from spreadsheet)




- The student enters a "1" in the line to indicate an electron or a muon event.
- She or he enters another "1" to discriminate between W+, W-, W (unknown charge), Z cand, ZZ cand, or zoo.
- Students should only enter "1's", not other numbers.
- Totals are made at the bottom of each section of 100 events in the spreadsheet tab. (Students should work in pairs, with each pair assigned a computer and 100 events to analyze.)
- Totals for all students in the Masterclass Institute are automatically transferred to the Results tab for the Institute. Institute totals are then transferred automatically to the Moderators tab for all Institutes sharing a particular videconference.
- Place "1's" to indicate parent particle data. Totals appear after last line of set. Next set (masterclass_2) follows, with a new background color. See below.

- When a student enters a "1" for "Z cand" or "H cand", an invariant mass will appear in the line. The student should then
- Round the mass to the nearest odd number value in GeV (e.g. 89.4 rounds to 89, as above).
- Go the the Massplot tab for his or her institute (e.g. Massplot Manhattan, as below) and find the rounded odd mass in the massplot data table. The student enters a "1" just above that mass. If there are any "1's" there already, the student adds his or hers just above the highest "1".
- The total of number of events at each mass is then automatically transferred to the mass plot in the Results tab.

- These numbers are also transferred to the Moderators tab for the mass plot for all Institutes sharing the videoconference.
- There should be more peaks in the mass plot than just the peak for the Z boson.
- Students have 60-90 minutes to analyze data. The mentor must reserve time for a discussion of results prior to the videoconference. This is more important than finishing the data analysis: once it is time for the all-hands discussion, student analysis must stop and the group should use whatever results they have at that point.
Presentation of results
Sample questions
- How many peaks are there in the mass plot?
- Where is the Z peak? What is the mass of the Z boson?
- What do the other peaks mean?
- Is there anything interesting in the 120-130 GeV range? What is it?
- What is the ratio of electrons to muons? Is it close to what we should expect?
- What is the W+/W- ratio? What should it be?
- Why are the widths or heights or numbers of peaks different from one Institute to the next?
- Why do different Institutes get different ratios? How did they identify electrons or muons or W candidates or Z candidates or zoo events? How did they measure charge for W candidates?
- Now that the Tevatron is shut down, what do you do at Fermilab?
- Is it boring at CERN when the LHC is not running?
- Why did you become a physicist?
Moderators
- Data - students record W or Z candidates, e or µ events, Z candidates, and "zoo" events. Choosing Z candidates results in masses popping up, which student round the the nearest odd number.
- Results - numbers of different types of particles are automatically transferred here; e/µ and W+/W- are calculated for the whole institute.
- Massplot - when a student gets a Z candidate mass and rounds it to the nearest odd integral value, he/she goes to this tab to place a "1" above that value. This builds up a mass plot.

- Speak clearly and succinctly
- Show your sense of humor
- Avoid explanations: draw ideas from students and then help them
- Encourage students to speak up, give their views, and back them up
- Mind the schedule
- Be friendly
- It is alright to disagree...with mentors, students, or each other
- Let students get a feel for how you see data and analysis
- Be familiar with the Masterclass measurement
- Show your enthusiasm
- Work as a team
Good advice with a CERN slant:

Masterclass Library Project Map 2014

The Masterclass Library contains most of the information needed for physicists and teachers to run a masterclass. The Project Map below is arranged in the typical chronological order in which a masterclass prepared and then carried out. The order is more descriptive than prescriptive.
The Project Map has 6 "metro stops" plus several associated branches. The main metro stops are:
- Library takes you to the Masterclass Library group of the QuarkNet website, with all of the documents and pages in reverse order of their creation.
- Orientation explains orienting of teachers and physicsts to run a masterclass and provides schedule information.
- Classroom Preparation details how teachers get their students ready for the masterclass.
- Institute and Videocon with their branches cover the main elements of the masterclass day. These make up the heart of the Project Map.
- Follow on shows what students can do to continue their exploration of particle physics after the masterclass.

Orientation 2014

Masterclass Orientation Period 2014: January 25 to March 8.
Go to: | Masterclass Library Pages:
|
New Institutes: Masterclass Orientation
A masterclass orienation can be done online via Vidyo or in person with a visit from a QuarkNet staff member or fellow. It is intended for teachers and mentors. Here is what is covered:
- Classroom prep for the masterclass
- Try out an ATLAS or CMS masterclass measurement
- Walk-through of masterclass logistics
- Masterclass Library
- Vidyo test
- Q&A
This generally takes 4-6 hours, though it can be trimmed or extended depending on needed. If you are doing a CMS or ATLAS Data Workshop in the masterclass orientation period, it counts as an orientation. If you had one previous to this, you only need an orientation update (below).
Register for Masterclass Orientation on the Google form at least one week prior to your earliest preferred date!
Experienced Institutes: Orientation Updates
An orientation update is to bring teachers and mentors up to speed on the latest in masterclass measurements and procedures. As orientation updates are done online, they also serve as Vidyo tests. Orientation updates take 1-2 hours.

Running a CMS WZH-path Masterclass

This page is primarily for mentors as they design the masterclass for their institutes.
Go to: | Masterclass Library Pages:
|
First things: iSPy and spreadsheets
Each computer should have robust internet access (preferred) or the DVD version of the masterclass loaded. Two students should work together at each computer to complete 100 events of the 1900-event sample.
Online:
- Students must have access to the event display program iSpy-online using the latest version of Firefox, Chrome, or Safari.
- Students must have access to the online spreadsheet. These will be linked from the schedule of CMS videoconferences under Data Analysis below.
- Students should have access to the CMS Masterclass website prior to the masterclass day.
Download versions:
- iso file (event display and data for DVD)
- zip file (compressed directory with event display and data in sub-directory)
Grab the data:
See Data Analysis, below.
Familiarize yourself:
- CMS Masterclass documentation
- CMS Masterclass website
- Try the measurement out with iSpy-online and the sandbox spreadsheet.
Share these with students when appropriate!
Students arrive
This should occupy the first 30-60 min
- Registration: please have students sign in (sample registration sheet)
- Gateway experience: have a cloud chamber, e/m apparatus, or something similar to whet interest
- Ice-breaker activity: students in small inhomogeneous groups create 1-2 good questions about particle physics, ATLAS, and/or LHC.
Shift training
Get students ready for their data analysis shift! This will take about 3 hours, though parts of it can be moved to other times of the day.
Mentor presentation, 30-60 min:
- keep it interactive - ask questions about prior experience, shows of hands, wild guesses, etc.
- give students something to touch, e.g. a wave-shifting fiber
- connect to classroom prep
- touch on standard model
- talk about your research
- template
Tour, 30-60 min:
- adds much to the day - often most popular part
- if you have an accelerator to show, great!
- if not: any interesting labs, even if not particle physics, are still great
- have enthusiastic grad students around to chat and explain
Analysis Prep (30-60 min):
- Have a teacher lead this if practical.
- Use/adapt the data analysis slides.
- Important: go through "masterclass-samples" in iSpy-online on the projector with the students:
- Show students how to navigate to a data file
- Discuss how to use the tools in iSpy-online (or iSpy-dvd)
- Discuss each event in terms of:
- Particle tracks, missing energy, ECal deposits, etc.
- Most likely parent particle (ask them what is what)
- Show how to record results on sample spreadsheet.
Lunch with a Physicist (30-60 min):
- This is also very popular and a great way for students to interact and get comfortable with scientists.
Data Analysis
This is the heart of the masterclass and takes 60-90 min. There should be 2 students at each computer, cooperating to get their data measured. Mentors, tutors, and teachers should circulate to help the students analyze the events and work out any problems they have. Don't give them answers. Help them figure things out and learn to see data as scientist does. Remind them that each event is a candidate Z, W, Higgs, or something else - not a definitively identified particle.
Online spreadsheets:
What if the spreadsheet we are supposed to use is jammed?
Go the the Spreadsheet Trouble page!
Note: Spreadsheets are open to edit, not only for student data analysis but for mentors and tutors to repair any issues.
Sharing Results
This takes a little over one hour. Both parts are important.
Discussion (30-45 min):
- Mentor leads, students interact
- Look at combined mass plots for your institute in spreadsheet.
- Help students point out peaks, bumps, significance; discuss results.
- Each institute is assigned another institute to question: look at their data as well. Students should form questions and comments.
Videoconference (30-45 min):
Connecting to videoconferences:
CERN | Fermilab |
---|---|
CMS masterclass institutes connecting to CERN will connect directly to Vidyo. Link/URL: http://tinyurl.com/mc14cernVC2. This is the updated version as of 12th March 2014.
|
CMS masterclass institutes connecting to Fermllab will do so via the following Indico pages:
|
Course of a videoconference:
- Connect to videoconference link or Indico page (see above).
- Someone should log into the videoconference 15 min early to be sure the connection is established. See the Schedules page.
- Follow the agenda on Indico:
- Introductions and warm-up
- Institute reports; questions from other institutes (assigned); questions by moderators
- Discussion, Q&A, and wrap-up
- It is good to have a student spokesperson but try to arrange so it is not too hard for another student to make a comment or ask a question.
After this, we have post-discussion and closeout. Have a nice day.
