Abstract

The latest results from the search for a Standard Model Higgs boson produced in association with a top quark pair ($\mathrm{t\bar{t}H}$) at $\sqrt{s} = 13$ TeV decaying to final states with multiple leptons is presented using the 2016 dataset from the CMS experiment. The Higgs decays into either WW*, ZZ*, or $\tau\tau$, and the top quark pair decays considered are either fully leptonic, or semi-leptonic. The leptons defining the final states are muons and/or electrons. The overall analysis strategy, as well as new techniques with respect to the 2015 results are outlined.
