Abstract
The discovery of a new boson at the LHC in 2012 has lead to an exciting time in high-energy particle physics. The first observations were in decays to γγ, WW, and ZZ and came with tests of spin parity and measurements of the new bosons mass. An important remaining question is the coupling of this boson to fermions. In this paper the current CMS results for Higgs boson decays to ττ, μμ and b¯b will be presented. These searches show an observed significance of 3.2 σ to ττ, 2.1 σ to b¯b and no significant excess to μμ. The combination of the ττ and b¯b results in a combined observed significance of 3.8 σ which gives strong evidence for the direct coupling of the 125GeV Higgs boson to down-type fermions.
