Abstract

In these proceedings to the LHCP conference 2013 results are presented on the study of the Higgs-like particle at a mass of 125 GeV decaying into final states consisting of either $\tau^+\tau^-$, or a $b\bar{b}$ quark pair, based on the full statistics of about 24 fb$^{-1}$, collected in 2011 and 2012 at 7 and 8 TeV respectively with the CMS experiment at the Large Hadron Collider. Leptonic and hadronic decay channels for the $\tau$-lepton are included in the search. Different production channels namely gluon fusion, vector boson fusion (VBF) and associated production with W/Z bosons have been studied $\tau^+\tau^-$ final states. The $b\bar{b}$ decay channel is studied in VBF as well as in associated production with W/Z and top quarks.
