Search for neutral MSSM higgs bosons in the tau tau final state

The talk will review the search for a neutral MSSM Higgs boson decaying to τ+τ− pair with 139 fb−1 of data collected by the ATLAS detector. Two production modes are considered, the gluon-fusion and b-associated production. Two channels are combined, the first where one τ lepton decaying leptonically and the other hadronically and the other where both τ’s decay hadronically. The results are interpreted in the minimal supersymmetric Standard Model (MSSM) model.
