You are all familiar with the compelling
physics case for the LHC
z Electroweak
symmetry breaking – Higgs?

For MH greater than ~200GeV discovery comes soon (H→4l)
For MH < 200 may take a few years at low luminosity (many ch)
Plenty of experimental issues: calibration, Etmiss, uniformity,…
The challenge is to be ready on day one!

Upgrade – Physics Motivation
z
Consider only luminosity upgrade
z
z
Extend LHC mass reach by ~30%
z
z
z
z
SM parameters, Higgs couplings
Parameter measurements for new physics (e.g. SUSY)
More demanding on detector upgrade because of pileup
environment
Increased sensitivity to rare processes and rare decay
modes
z
z
Less demanding on detector upgrade because of robust signals
Improve on precision measurements
z
z
1034 → 1035 cm-2s-1
More demanding on detector upgrade because of pileup
environment
