Abstract:
On July 4, 2012, the LHC experiments ATLAS and CMS announced the discovery of a new particle. After its discovery the properties of the particle have to be determined in order to establish experimentally if it is really the Higgs boson, i.e. the particle responsible for the creation of particle masses without violating gauge principles. I will review in this talk the program of the experimental verification of the Higgs mechanism at the LHC: the determination of the Higgs boson couplings to the other Standard Model (SM) particles, the determination of the spin and CP quantum numbers of the newly discovered particle, and, finally, the determination of the Higgs self-couplings. The determination of the Higgs boson properties will also reveal if it is the Higgs particle of the SM or the one of a (possibly extended) Higgs sector of beyond the SM physics.
