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.
Special one day version (Spanish only)
- gain knowledge and skills to successfully complete investigations using LHC data;
- interpret event displays from CMS and explain their meaning;
- conduct LHC investigations with students and successfully prepare them for masterclass; and
- assist mentors in organizing and facilitating a masterclass.

Study the W bosons produced in the Large Hadron Collider.
Tiny URL for this page: http://tinyurl.com/lnwmrf8
Protons collide with incredible energy in the Large Hadron Collider. Sometimes the result of one of these collisions is a W boson - the particle which mediates the weak nuclear interaction. W bosons can be positive (+) or negative (-) in charge. But...
- How often are W+ bosons made compared to W- bosons in the the LHC?
- Should it be equal because nature has no preference?
- Should we see all W+ because the proton is positive?
- Can we find out?
- Learn a little about LHC, the CMS detector, and finding W candidate events. Look at the introductory slides.
- Make teams of two and divide the available CMS events among the teams. Each team also gets a report page.
- Characterize your events and count them:
- W+ candidates have a single long red muon track which curves clockwise in the magnetic field of CMS.
- W- candidates have a single long red muon track which curves anti-clockwise in the magnetic field of CMS.
- W? events are too hard to measure so we cannot tell if they are W+ or W-.
- Background events have more than one muon or are altogether different.
- Add them up on the report page. Then collect all the reports from all the teams and add up the number of W+ candidates and the number of W- candidates. Calculate W+/W-. If you like, you can use this spreadsheet.
- Find what the result was for CMS. How close was your group? Why do you think we get the answer we get? (Hint: it has to do with the structure of the proton,)
- Did you notice the mass in GeV on each event? We use these to find the mass of the Z boson in the standard CMS Data Express. Try it with your students!
- Your students can do even more with a CMS or ATLAS masterclass. Talk with a physicist near you about International Masterclasses.
- For a more intense data experience, try the CMS e-Lab.
- Have questions about this activity? Send an e-mail and ask.

Questions? Follow-up? More?
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.
- 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.
- 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.
