Submitted by kcecire
on Monday, October 8, 2012 - 10:48
This is where LHC and Neutrino fellows try out ideas, build agenda pages, and keep our important docs.
Description
Development and utilities for the QuarkNet LHC fellows.
LIGO e-Lab workshop template 2017

Dates, 2017
Objectives
Participating teachers will be able to:
- Plot and interpret data recorded by LIGO seismic instruments; address limitations in the data.
- Make claims based on evidence from LIGO data and provide reasoning.
- Explain the importance of LIGO seismic data in a gravitiational wave search
- Use LIGO seismic data to demonstrate classical physics concepts
- Develop a plan to use material from the workshop in school.
Agenda
Times and specific activities are subject to adjustment.

Recommendations for a Successful CMS MasterclassN students - N≤30 - N/2 computers - N/10 mentors/tutors
The optimal number of students is about 30 or fewer. It is possible to have more but please proceed cautiously.
Two students to a computer: they can help each other and check each other's judgements.
At least one physicist to every 10 students. In some cases, a teacher with a developed background in masterclasses can help bend this ratio. |

LHC fellows work session, 5-7 August 2016

- Friday 5 August:
- 09:00-12:00 CT at Fermilab
- 13:00-18:00 CT go to work in Chicago
- Satuarday 6 August, 09:00-17:00 CT at Fermilab
- Sunday, 7 August in Chicago - see special QN@ICHEP agenda
- World Wide Data Day planning - ATLAS and CMS masterclass-in-a-box
- date
- measurement(s)
- logistics
- videos for engagement: Spotlight on hardware and big picture "Path of the protons"
- CMS Masterclass measurement and website
- revisions to measurement
- revisions to website
- CMS e-Lab (current) (development)
- revisions to project map resources - includes new screencasts
- finalize use of new interface
- see notes below
- IMC2017 planning
- neutrino masterclass brainstorming
- Data portfolio threads: ATLAS, CMS, LIGO, neutrino, other
- General discussions
We will set priorities each morning and divde the work up by small teams, checking in with each other frequently and reporting at the end of the day. We will not likely get everything done but we will make a real, helpful progress..
Notes from Sudha Balakrishnan on needed items for CMS e-Lab:
- Milestones: Choose a study. BTW, the logbook will be inaccurate until all the Milestones are fixed.
- Milestones: Select Data.
- Milestone: Choose appropriate analysis tool.
- http://i2u2-dev.crc.nd.edu/elab/cms/data/ (Index page when you click 'Data'). Does this need any change? Is it ok as-is on dev?
- Library-Resources section:
- Calibration Studies screencast - remove?
- Exploration Studies screencast - replace?
- 3-D Event Display screencast - is it up to date?
- Contextual Help with the Analysis, like we have with the current version (under the Help question mark)? In dev, it seems to be on the page, but it goes to the old screencasts. cms/videos/demo-exploration.html provides access to 4 different videos.
- Site index: There's no calibration anymore.
- Explore! page needs to be updated.
- Site Tips: Update special icons, like 'Help?'.

ATLAS Data Express Draft

Introduction
ATLAS Data Express is a short particle physics masterclass investigation that can be used as part of a workshop or as a short class project. Participants examine static displays of a limited number of events. The main goal is to separate Z candidate events other events by visual inspection and then create mass plot for the Z boson.
The Z boson is important in LHC discovery science and as a marker for calibration of LHC detectors: it is a well-known particle, so the location and width of the mass plot give physicists a good idea of how the detector is performing. The Z candidate events we will study are "dimuon" events; the Z can decay into a muon-antimuon pair. Z candidates are identified by 2 long muon tracks; each will appear as a combination of a short blue track in the inner detector (inner black ring) and a longer orange track in the outer muon chambers (blue rings). Participants will search for Z candidates in the data.
Instructions
Individual or pair:
- Participate in analysis prep seminar (slides) (ATLAS animation)
- Open the event display file
- Go to set of events assigned
- Categorize and record each event as
- Z → μ+μ- candidate (2 distinct muon tracks),
- background (anything else).
- For each Z candidate, note and record
- the mass, rounded to nearest odd number (found at upper right of event)
- whether it is an electron or a muon event.
- When finished, count how many instances of each odd number you have recorded.
Group:
Use your own resources to
- Combine numbers of "odd masses" in all groups.
- Create a histogram for whole group to observe.
- Analyze other aspects of the data (optional).
Help: Use the Google spreadsheet.
Discussion
The histogram created by the group is a mass plot. Since the mass of any one type of particle is uncertain by nature and due to experimental uncertainty, it will have a distribution the peak of which is the experimental determination of the mass. Creation of mass plots and other histograms are the central measurements made in the CMS e-Lab but with many more events than used in this exercise.

Objectives
Workshop participants will:
- Identify particles colliding and emerging from collisions at the LHC from CMS data.
- Interpret the physical meaning of plots created from CMS data in light of conservation rules (energy, momentum, charge).
- Ask and answer questions about the physics of high energy collisions using CMS data.
