Higgs boson parameters and decays into fermions

In 2012 the discovery of a new boson with a mass of about 125 GeV and properties in agreement with those expected for the Higgs boson in the standard model was announced. In this note we review the results of searches for the fermionic decays the Higgs boson and the study of its properties performed...

description In 2012 the discovery of a new boson with a mass of about 125 GeV and properties in agreement with those expected for the Higgs boson in the standard model was announced. In this note we review the results of searches for the fermionic decays the Higgs boson and the study of its properties performed with the proton-proton collision data recorded by the ATLAS and CMS detectors at the LHC in 2011 and 2012, corresponding to an integrated luminosity of approximately 5~fb$^{-1}$ and approximately 20~fb$^{-1}$ per experiment at $\sqrt{s}=7$~TeV and $\sqrt{s}=8$~TeV, respectively. Decay rates to fermions and extracted couplings are consistent with the expectation of the standard model. In addition, we present a search for lepton flavour violating decays of the Higgs boson which can occur in several extensions of the standard model, and a search for neutral Higgs bosons decaying to tau pairs performed in the context of the minimal supersymmetric extension of the standard model (MSSM).
