A Schematic detector
Calorimeter Induces shower in dense material
Muon detector
Tracking system Magnetized volume
Interaction point
Innermost tracking layers use silicon
EM layers fine sampling
Absorber material
Hadronic layers
Electron
Experimental signature of a quark or gluon
Jet q or g
Bend angle ? momentum
Muon
Missing transverse energy
Signature of a non-interacting (or
weakly interacting) particle like a neutrino

Collisions at the Tevatron
proton
anti-proton

• Advantages (re ee-)
• High Energy
• Hard Scatter is QCD

• Disadvantages (re ee-)
• Dont know whats colliding
• Underlying Event
• Hard Scatter is QCD
