Particle Physics Masterclasses
APS Division of Particles and Fields2011 Meeting, Providence

Masterclasses in Particle Physics
• Students are “physicists-for-a-day” at university or lab.
• Analyze real CERN data.• Like a masterclass in the
arts• Finish with video
conference with other masterclass institutes.
Until 2011, the particle physics masterclasses had students investigate the branching ratios of the Z boson using event displays from real LEP data.

LHC Masterclasses
ATLAS Z Path• Students search for Z
candidates.• Create mass plot.• Look for peak, width, and
unexpected bumps.
ATLAS W Path• Students count W+ vs, W-.• Find ratio.• Probe structure of proton.

LHC Masterclasses
CMS J/Y Path• Students rate dimuon
events, 2-5 GeV.• Choose which to use in
mass plot.• Compare result.
ALICE• Search for strange particles.• L and K0
s mass plots

Results and Future• 2011 Masterclasses:
– General satisfaction with exercises and real LHC data
– Worked out some issues with first run.
• Moving forward: – CMS: Develop W/Z
exercise; more data available
– ATLAS new approach to W exercise
