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 $\mathrm{b}\bar{\mathrm{b}}$ will be presented. These searches show an observed significance of 3.2 $\sigma$ to $\tau\tau$, 2.1 $\sigma$ to $\mathrm{b}\bar{\mathrm{b}}$ and no significant excess to $\mu\mu$. The combination of the $\tau\tau$ and $\mathrm{b}\bar{\mathrm{b}}$ results in a combined observed significance of 3.8 $\sigma$ which gives strong evidence for the direct coupling of the 125 GeV Higgs boson to down-type fermions.
