Introduction

Data Workshops are workshops for teacher with physicists participating. They take a recommended 8-12 hours and are designed to be facilitated by a QuarkNet staff member or fellow. Data Workshops have been done both in and outside the U.S. with some success. For masterclasses, the Data Workshop provides the most thorough orientation for both teachers and mentors. Outside of masterclasses, they give teachers insights into how to bring particle physics data to their students in a way that enables them to start to look at the data as physicists might. 

Please note that this document is subject to revision based on evaluation data.

Flavors

• ATLAS
• CMS
• Teaching and Learning
• other

Objectives

Overall

Both objectives apply to all Data Worshops.

Teachers will be able to:

• expose students to the introductory physics concepts used in high-energy physics
• lead students in investigations using data from particle physics experiments.

Flavor-specific

Choose one of these depending on the flavor of the workshop, though others may apply as unstated objectives.

Participating teachers are able to:

• interpret event displays from ATLAS/CMS and explain their meaning (ATLAS or CMS)
• prepare students for and assist mentors in facilitating a masterclass (ATLAS or CMS)
• use and design activities that incorporate scientific inquiry. (Teaching and Learning)

Notes on objectives

• The Data Portfolio is not mentioned in this version of objectives but is incorporated as a key resource and organizing principle.
• Flavor-specific objectives are not mutually exclusive. For example, "use and design activities that incorporate scientific inquiry" can be a stated or unstated objective of a CMS Data Workshop.
• Some activities may go beyond the stated objectives but support and enhance them. For example, an ATLAS Virtual Visit may not give teachers additional skills toward doing activities with students but serve as an important affective link to the actual experiment and the people who perform it. 

Agenda

Notes on Agenda items

• There are 3 standard Level 1 activities listed in the First Day. 
• An example of an Advanced Level 1 activity might be Mass Calc Z. Another, not in currently in the Data Portfolio, is CMS Data Express.
• The number of Level 1 actviities of any type may vary.
• Masterclass and e-Lab are specficied here as they are main types of Level 2 and 3 activities.
• In this case, "e-Lab activity" can refer to a specific activity using an e-Lab, e.g. cosmic activities developed for the ILC workshops in Japan in June 2014.

Resources

Spine

• Data Portfolio
• PPT or PDF in support of workshop (e.g. Introduction/Objectives for CMS) 

Additional workshop components

• non-Portfolio or activities (e.g., for now, CMS Data Express)
• Documents in support of related content (e.g. CERN Guide to LHC)

Additional resources for classroom

These may also be used in the workshop as enhancements. Examples include:

• CMS website
• ATLAS detector animation
• Large Hadron rap

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.

Resources

• Histograms
• Units in particle physics
• Events
• ATLAS Masterclass Analysis Prep

Agenda elemnts:

1. ATLAS or CMS virtual visit with an engineer
2. Making it 'round the bend
3. Design problem - getting to high field
4. Calorimeter actvity
5. Design problem - stopping high energy particles
6. Testing activity (with ODUs? fiber? CRMD blessing and perf?)
7. Tie together; discussion
