Sumario:The latest results of the search for the standard model scalar boson in fermionic decay channels at the CMS experiment are presented. The dataset used corresponds to an integrated luminosity of 5 $fb^{-1}$ of proton-proton collision data collected at $\sqrt{s}$ = 7 TeV and up to 19.4 $fb^{-1}$ collected at $\sqrt{s}$ = 8 TeV. The analyses described include the searches for the standard model scalar decaying to tau pairs and to a pair of b-quarks. In the tau-pair nal state, an excess of events is observed over a broad range of SM scalar mass hypotheses, with a maximum local signicance of 2.93 standard deviations at $m_H$ = 120 GeV. The excess is compatible with the presence of a standard model scalar boson of mass 125 GeV.
