SEMINAR: Mining the Golden Channel: Searching for New Physics in Higgs decays to four leptons

May 15 2015, 12:00pm - Seminar room

Speaker: Roberto Vega-Morales (LPT-Orsay, Paris)

Abstract : An overview of various physics possibilities in the Higgs to four leptons 'golden channel' decay will be presented and discussed. First we analyze effective Higgs couplings to neutral electroweak gauge bosons​.

The prospects for measuring the CP properties of the Higgs couplings to ZZ, Z photon, and photon photon pairs​ at the LHC will be discussed. We then discuss the possibility of probing the underlying loop effects which generate these effective couplings. In particular the ability of the golden channel to probe the top Yukawa CP properties and the Higgs coupling to WW pairs will be discussed.
