Interplay: LHC Intensity Frontier

Intensity Frontier

Only handle on the next energy scale

Determine/verify structure of new physics. Anything beyond?

Example: early discovery at LHC

•  LHC discovers strongly coupled SUSY

•  A host of new particles: fit roughly some masses, make assumption on couplings
