Abstract
With the increase of the integrated luminosity recorded by LHC, the research of possible dark-matter candidates assumes more and more importance. In simplified dark-matter production models, dark matter is produced from the decay of a mediator, coupled both to standard model particles and dark matter. For scalar and pseudoscalar mediators, the associate production of dark matter and two top quarks gives an excellent sensitivity on a wide range of model parameters, mainly thanks to the high top quark Yukawa coupling. In particular the analyses are focused on the top quark decays in zero, one and two leptons. In this contribution, updates concerning the most recent ATLAS results based on 13 fb−1 of 13 TeV LHC data are given.
