Search for the standard model Higgs boson produced in association with top quarks at CMS

The search for the standard model Higgs boson produced in association with a top-quark pair is presented, using up to 5 $\mathrm{fb^{-1}}$ and 19.6 $\mathrm{fb^{-1}}$ of 7 and 8\,TeV pp collision data collected by the CMS experiment at the LHC. The search is performed in several channels characterised by different combinations of the decay products of the top-quark pair and the Higgs boson. The decay channels of the Higgs boson into $\mathrm{b\bar{b}}$, $\tau\tau$, $\gamma\gamma$, $\mathrm{ZZ}^{*}$, and $\mathrm{WW}^{*}$ are investigated. The signal strength $\mu$, relative to the expectation for the standard model Higgs boson production is measured to be $\mu=2.5^{+1.1}_{-1.0}$ for a Higgs boson mass of 125 $\mathrm{GeV}$.
