### Description

This talk will cover the latest result of searching for heavy Higgs decaying to two tau leptons with the ATLAS full Run2 datasets using pp collison at $\sqrt(s)$ = 13 TeV. This search is performed over the mass range of 0.2-2.5 TeV and the two $\tau$ leptons decay is considered, where at least one $\tau$ decays leptonically. This channel is sensitive at high $\tan\beta$ value acoording to hMSSM and other 2HDMs, where $\tan\beta$ is the ratio of the vacuum expectation values of the two Higgs. The results of this search show that most of the parameter space of hMSSM is excluded with 95% CL.
