Description
The discovery of a Higgs boson, consistent with the Standard Model, has heralded a new era in which fundamental scalar fields may be safely called to play a central rôle to solve long-lasting physics questions : grand unification of forces, supersymmetry, dark matter, cosmic inflation... To express it in other words, if the sophisticated Brout-Englert-Higgs mechanism really works as we believe it should, it would be very strange that Nature has used it only once to break the U(1) x SU(2) symmetry ! Searching for the existence of extra Higgs (scalar) bosons - be they neutral or charged – has then become one of the research lines that could plausibly deliver fruitful results in the coming years.
On behalf of the ATLAS and CMS collaborations, I will present the most striking results and the best limits obtained up to now at LHC in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. I will conclude my presentation by a few words on the LHC discovery potential – with respect to new Higgses – in the coming 3 to 4 years.
