Les Houches

Interested people: Roberto, Yun, … (please add your name!)

Topics:

1) check feasability of WW→hh: which channel (WWbb) ? which luminosity ? is energy upgrade competitive ?

2) sensitivity on trilinear (HH)^3 in gg→hh vs gg→h (at two loops): by the time we are able to measure it, will gg→hh be competitive with single higgs ?

3) check extraction of anomalous couplings (e.g. cH) using double Higgs strahlung at the LHC

4) effect of resonances (ex: heavy scalar decaying to hh) in double-Higgs production
