Abstract:

A search for the production for a standard model Higgs boson in association with a top quark pair (

\mathrm{t}\overline{\mathrm{t}}\mathrm{H}

) is presented. The analysis is based on pp collision data collected by the CMS experiment at a center of mass energy of

\sqrt{s}=13~\mathrm{TeV}

in 2016, and corresponding to an integrated luminosity of

35.9~\mathrm{fb}^{-1}

. We target final states where the Higgs boson decays to

\mathrm{WW}^{*}

,

\mathrm{ZZ}^{*}

or

\tau\tau

, and at least one of the top quarks decays leptonically, by selecting events with two leptons of the same charge, three leptons or at least four leptons, and b-jets. We obtain a best fit

\mathrm{t}\overline{\mathrm{t}}\mathrm{H}

yield of

1.5~\pm~0.5

times the standard model prediction, with an observed (expected) significance of

3.3\sigma

(

2.5\sigma

), by the combination of these results with those obtained from the 2015 dataset.
