| Abstract: A search for dark matter particles produced in association with a Higgs boson decaying into a pair of $ \tau $ leptons is performed using data collected in proton-proton collisions with the CMS detector at a center-of-mass energy of 13 TeV. The analysis is based on a data set corresponding to an integrated luminosity of 101 fb$ ^{-1} $ collected in 2017--2018 with the CMS detector. No significant excess over the expected standard model background is observed. This result is interpreted within the framework of two benchmark simplified models: the baryonic-Z' and 2HDM+a models. Upper limits at the 95% confidence level are set on the product of the production cross section and branching fraction in the two simplified models. For the baryonic-Z' model, a statistical combination is made with an earlier search based on a data set of 36 fb$ ^{-1} $ collected in 2016. In this model, Z' masses up to 1050 GeV are excluded for a dark matter particle mass of 1 GeV. In the 2HDM+a model, heavy pseudoscalar masses between 400 and 700 GeV are excluded for a light pseudoscalar mass of 100 GeV. | ||
