The analysis uses 139 fb−1 of proton-proton collision data at p √s = 13TeV collected by the ATLAS experiment at the Large Hadron Collider between 2015 and 2018. No evidence of physics beyond the Standard Model is found. The results are interpreted in terms of a 2HDM+a model featuring two scalar Higgs doublets and a pseudoscalar singlet field. Exclusion limits on the parameters of the model in selected benchmark scenarios are derived at 95% confidence level. Model-independent limits are also set on the visible crosssection for processes beyond the Standard Model producing missing transverse momentum in association with a Higgs boson decaying into τ-leptons.}, organization = {CERN}, organization = {MICINN}, organization = {Horizon 2020}, organization = {Marie Skłodowska-Curie Actions}, organization = {La Caixa Banking Foundation}, organization = {CERCA Programme Generalitat de Catalunya}, organization = {PROMETEO and GenT Programmes Generalitat Valenciana}, publisher = {Springer Nature}, keywords = {Hadron-Hadron Scattering}, title = {Search for dark matter produced in association with a Higgs boson decaying to tau leptons at √s = 13 TeV with the ATLAS detector}, doi = {10.1007/JHEP09(2023)189}, author = {Aad, Georges and Aguilar Saavedra, Juan Antonio and Rodríguez Chala, Mikael and Atlas Collaboration, /}, }
