Vanderbilt University July 26, 2010 A look at the Masterclass From LEP to LHC

Vanderbilt University July 26, What is the Masterclass? As in a masterclass in the arts, students work with an expert. Expert = particle physicist. Instead of, say, a violin, the subject is particle physics data analysis. Masterclass

Vanderbilt University July 26, Masterclass Day – sample agenda TIME:ACTIVITY: 8:00-8:30 Registration & Welcome Cloud Chamber Demo 8:30-9:30Introduction to Particle Physics (Mentor) 9:30-11:00Tour 11:00-12:00 Introduction to Data Analysis (Teacher) 12:00-13:00Lunch with a Physicist 13:00-15:00 Data Analysis Results Transmission 15:00-15:30 EVO Logon Questions & Discussion Points Preparation 15:30-16:30EVO Videoconference 16:30-17:00Evaluation & Closing Masterclass

Vanderbilt University July 26, 2010 Standard Model Quarks combine to make hadrons (protons, neutrons,…) Leptons – electron and its heavier cousins – and the small, unseen neutrinos Force carriers (the bosons) Heavier particles can “decay” into lighter particles. Masterclass

Vanderbilt University July 26, 2010 What’s that, up in the sky? What’s it doing? What time is it? How do you know? Are you sure? What does this have to do with particle physics? Masterclass

Vanderbilt University July 26, 2010 Generic Detector Design Cylinders wrapped around the beam pipe From inner to outer... Tracking Magnet Electromagnetic calorimeter Hadronic calorimeter Muon chamber Masterclass

Vanderbilt University July 26, 2010

Vanderbilt University July 26, 2010 DELPHI at LEP: Our Z Lab The beam particles each had a total energy of 45.5 GeV: LEP built Z bosons—they promptly decayed. The detectors measured the stuff that came out of the decay. 2 x 45.5 GeV = 91.1 GeV 91.1 GeV is the Z mass. Masterclass

Vanderbilt University July 26, 2010 Z  2 muons Z  2 electrons Masterclass

Vanderbilt University July 26, 2010 What’s what? Z  2 electrons Z  2 muons Z  other stuff Masterclass

Vanderbilt University July 26, 2010 What’s what? Z  2 electrons Z  2 muons Z  other stuff Masterclass

Vanderbilt University July 26, 2010 What’s what? Z  2 electrons Z  2 muons Z  other stuff What’s the count? Masterclass

Vanderbilt University July 26, 2010 Next steps for students: Practice. Talk with your fellow physicists. Make teams of two. Analyze up to 1000 events (as a group). Report! Rapport! Rejoice! Relax! Masterclass

Vanderbilt University July 26, 2010 What’s new? LHC Masterclass Students look at Z- and W-decays Test the new accelerator and detectors This is what physicists are doing right now… Masterclass

Vanderbilt University July 26, 2010 The Plan Express interest/preferences Orientation Video/audio test Prepare students Masterclass here in March Participate with –Around 20 QN centers –Hundreds of MC institutes worldwide –2 to 4 Institutes on your day Masterclass, forward
