Abstract:

A search for the standard model Higgs boson produced in association with a top quark pair is presented. Data collected by the CMS experiment in

\mathrm{pp}

collisions at a center of mass energy of

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

and corresponding to an integrated luminosity of 2.3~fb

^{-1}

are used. The analysis targets the

\mathrm{WW}^{*}

,

\mathrm{ZZ}^{*}

and

\tau\tau

decay channels of the Higgs boson by selecting final states with two same-sign leptons or more than three leptons, produced in association with b jets. The signal strength is measured to be

0.6^{+1.4}_{-1.1}

times the standard model expectation. The observed 95\% confidence level upper limit on the

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

production cross section is 3.3 times the standard model expectation, compared to the 2.6 expected in absence of a signal.
