1 Recent Progress from CMS-China
Yajun Mao For CMS China Group The analysis has been performed on the pp-collision data sample recorded by the CMS detector at the center-of-mass energy of 8TeV, corresponding to an integrated luminosity of 19.3fb-1. The obtained results are interpreted as a search for a SM higgs boson, as well as in the context of a beyond the SM scenario, based on an effective theory where a second scalar particle besides the resonance at 125GeV completes the unitarization of the WW scattering 2nd CLHCP Workshop
