### Description

A search for the associated production of a standard model Higgs boson and a top quark-anti quark pair (ttH), using LHC pp collision data collected by the CMS experiment at a center of mass energy of 13 TeV in 2016. The dataset corresponds to an integrated luminosity of 12.9 fb$^{-1}$ . The analysis uses events with two leptons of the same charge or at least three charged leptons, produced together with b jets, targeting Higgs boson decay modes to WW$^{∗}$ , ZZ$^{∗}$ , and ττ and leptonic decays of at least one of the top quarks. The results are combined with the 2015 dataset/ The signal strength and a 95% confidence level upper limit on the signal production cross section are presented
