Descripción
A search for a Higgs boson production in assotiation with a top-antitop quark pair is presented in pp collisions at $\sqrt{s} = $ 13 TeV recorded by CMS. We target topologies in which the scalar boson decays into $WW^*$, $ZZ^*$ and $\tau\tau$ and at least one of the top quarks decays leptonically by selecting events with two same-sign, three or four leptons in the final state. The search results in a measured cross-section of $1.5 \pm 0.5$ times the expectations of the Standard Model, which corresponds to 3 standard deviations with respect to the no $t\bar{t}H$ production hypothesis.
