The Matrix Element Method used in the search for the associated production of the Higgs boson with top quarks and decaying into tau leptons

Latest results of CMS searches for a Higgs boson produced in association with top quarks in final states with tau leptons are reported. This contribution will specifically focus on technical aspects related to the Matrix Element Method implementation and on its impact on the sensitivity of the analysis. The analysis presented here uses proton-proton collision data collected at center-of-mass energies of 13 TeV during the Run II of the LHC collected by the CMS experiment in 2016. An excess has been observed with respect to the background-only hypothesis in the multilepton final states 3.2$\sigma$ observed significance (2.8$\sigma$ expected).
