  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.
