Abstract

In this paper, the latest results of searches for the standard model Higgs boson produced in association with a top quark-antiquark pair ($\mathrm{t\bar{t}H}$), where Higgs decays into photons, bottom quark-antiquark pair or leptons via $\mathrm{WW^*}$, $\mathrm{ZZ^*}$ and $\mathrm{\tau\tau}$ will be presented. The analyses have been performed using the $\mathrm{13\,TeV}$ pp collisions data recorded by the CMS experiment in 2015 and part of 2016. The results are presented in the form of the best fit to the signal strength ($\mathrm{\mu=\sigma/\sigma_{SM}}$) measured with respect to the Standard Model prediction and its expected and observed $\mathrm{95\%}$ C.L. upper limits.
