A measurement of the Standard Model Higgs boson produced in association with a W or Z boson and decaying into a pair of ττ-leptons is presented. This search is based on proton-proton collision data collected at √s ​=13 TeV by the ATLAS experiment at the LHC corresponding to an integrated luminosity of 140 fb−1. For the Higgs boson candidate, only final states with at least one ττ-lepton decaying hadronically (τ→hadrons+νττ→hadrons+ντ​) are considered. For the vector bosons, only leptonic decay channels are considered: Z→ℓℓ and W→ℓνℓ​, with ℓ=e,μ. An excess of events over the expected background is found with an observed (expected) significance of 4.2 (3.6) standard deviations, providing evidence of the Higgs boson produced in association with a vector boson and decaying into a pair of τ-leptons.
