Higgs potential and BSM opportunity 希格斯物理研讨会

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.
