Event Description
The observation of a Higgs boson by the LHC experiments through its decays to vector bosons was an extremely significant milestone in particle physics research; one which redefined the research priorities in the field. After this discovery the first step was to test the compatibility of the new particle with the SM Higgs by searching for the different possible Higgs couplings. The decay to fermions is of fundamental importance since it proves the presence of Yukawa couplings in the theory. Since Higgs couples to mass, it breaks lepton universality, therefore decays to tau leptons are enhanced. The next step is to use the Higgs as a tool for new physics searches through its decays (i.e. lepton flavor violation) or through its associated production with other particles (A->Zh, H->hh, etc.) The experimental challenges of triggering and identifying tau leptons will be described. Then the recent Higgs results will be presented for the SM Higgs and the SUSY extensions. Finally, the future prospects of Higgs and tau physics will be summarized.
