When QuarkNet does a workshop or other project that falls outside the current parameters, it can have a QuarkNet home here.

QuarkNet projects outside of center or data portfolio groups.
ILC and Higgs
Introduction
The International Linear Collider (ILC) will give physicists a new way to study the Higgs boson with great precision. The ILC will be an electron-positron collider. Electrons and positrons will be produced and then accelerated to high energies before they collide. A result of these collisions can be the Higgs boson. To understand what physicists will look for to find the Higgs signal in ILC, we will examine Z and WW decays from the Large Electron Positron collider (LEP), which operated until 1999 in the tunnel which now houses the Large Hadron Collider.
Objectives
Participants will:
- Use conservation laws to explain and characterize the decays of Z and W bosons in LEP.
- Use the hypotheses formed about Z and W decays to predict the patterns of Higgs boson event in ILC.
Workflow
- LEP Z-decay. Examine the slides of decays of Z-bosons and try to characterize the patterns according to decay products (particles), number of tracks, energy loss, and anything else you observe. This does not all have to be quantitative. Take notes. Discuss and form a consensus on how the Z boson decays. Resources: Slides (original, inverted colors), Information sheet, Notes sheet.
- LEP WW-decay. Examine the slides of decays of pairs of W-bosons and try to characterize the patterns according to decay products (particles), number of tracks, energy loss, and anything else you observe. This does not all have to be quantitative. Take notes. Discuss and form a consensus on how the W boson pairs decay. Resources: Slides (original, inverted colors), Information sheet, Notes sheet.
- Higgs in ILC. Examine the ILC/Higgs slides to learn how the Higgs boson will be produced in ILC. Use what you have learned from LEP events to predict what the Higgs events in ILC will look like. Draw diagrams and share these with your colleagues. Resources: Slides, Information sheet, Notes sheet, poster board, markers.

Requirements for a successful cosmic ray detector workshop
Construction
Items needed:
- If constructing detector(s):
- CRMD kit
- 6000 series CRMD assembly instructions (included with CRMD kit)
- tools:
- multi-meter (digital, accurate to 0.01 v or better)
- scissors
- ruler or meter stick
- sandpaper
- "tongue-depressor" stick (in CRMD kit)
- razor or box cutters
- tape measure (50ft/20m)
- protractor
- extra cotton gloves for handling scintillator
- optional: oscilloscope
- supplies:
- 3/4" (~2 cm) and 3" (~8 cm) electrical tape -- black vinyl
- ** 1/2" (~1.3 cm) teflon plumbing tape
- power strip(s) for computers and CRMD
- good room to construct and setup the detector with table top space
- access to the outside for placement of the GPS receiver: must have clear view of the sky and within 75 feet of the detector for cable run (antenna can look through a window)
- one computer with USB port for talking to the detector and capturing data
- USB drive for each teacher to upload data and download online files
- verify: data computer will not go into 'sleep' mode; Windows: check 'Control Panel'
- need apps: 'hyperterm' on Win; 'ZTerm' on Mac. These can be downloaded free.
- USB drivers installed on data computers for “6000” series DAQ, found at:
- User agreement for teacher who will use the detector at school
Venue
Needed for the e-Lab workshop:
- build teacher accounts ahead of time. Need:
- name:
- school:
- city/state/province/prefecture:
- email:
- preferred login name:
- send to: rspete@fnal.gov
- You may use this spreadsheet: Tchrdata.xls
- access for facilitator machine on the local network
- computer access for each participant with internet (IT staff available: trouble-shooting)
- root access to each computer for installing apps and rebooting.
- ability to print e-Lab resources
- LCD projector: two would be best, but one is OK
- black/white board & markers
- Print:
- CRMD quick-start guide (draft for use if not constructing CRMD)
- CRMD user manuals (print for working groups)
- Cosmic Extremes, resource for each teacher
- evaluation forms (and translate?)
Other considerations:
- Set-up and clean-up of room
- Name tags (optional but helpful; romaji kudasai)
- Tables, outlets, lighting, space, etc.
- Computers for detectors and presentation (QuarkNet team may have sufficient for presentation)
- Projector and screen
- Internet Access (important)
- Notebooks/pens/markers (participants bring?)
- Venue and/or Parking Passes if Necessary
- Food related: tea, snack, lunch?
Important Human Elements:
- Physicist to give teachers a talk on cosmic rays
- Presence of local physicist-mentor(s) for teachers
- Continued communication after the workshop
- Translator(s) are helpful for international workshops
