( 0++ dominance ; C,P- even) H ->bb opens up ( Hbb- coupl. ) (gg) CED  bb in LO ; NLO,NNLO, b- mass effects - controllable. For some areas of the MSSM param. space CEDP may become a discovery channel ! H → WW */ WW - an added value ( less challenging experimentally + small bgds., better PU cond. ) New leverage –proton momentum correlations ( probes of QCD dynamics, CP- violation effects… )  LHC : ‘after discovery stage’, Higgs ID …… H How do we know what we’ve found? mass, spin, couplings to fermions and Gauge Bosons, invisible modes …  for all these purposes the CEDP will be particularly handy ! CED Higgs production at the LHC
