Search for a Higgs to Fermions with the CMS detector at the LHC

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 gamma gamma, 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 tau tau, mu mu and b (b) over bar will be presented. These searches show an observed significance of 3.2 sigma to tau tau, 2.1 s to b (b) over bar and no significant excess to mu mu. The combination of the tau tau and b (b) over bar results in a ombined observed significance of 3.8 sigma which gives strong evidence for the direct coupling of the 125GeV Higgs boson to down-type fermions.
