Studies of the ttH production at 13 TeV

The latest results of searches for the standard model Higgs boson produced in association with a top quark-antiquark pair ($t\bar{t}H$), where Higgs decays into photons, bottom quark-antiquark pair or leptons via WW, ZZ and $\tau\tau$ are presented. The analyses have been performed using the $13\,TeV$ 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 ($\mu=\sigma/\sigma_{SM}$) measured with respect to the Standard Model prediction and its expected and observed 95% CL upper limits.
