Search for dark matter produced in association with bottom or top quarks in = 13 TeV pp collisions with the ATLAS detector
Abstract
A search for weakly-interacting-massive-particle (WIMP) dark matter produced in association with bottom or top quarks is presented. Final states containing third generation quarks and missing transverse momentum are considered. The analysis uses 36.1 fb-1 of proton-proton collisions data recorded by the ATLAS experiment at sqrt(s)=13 TeV in 2015 and 2016. No significant deviation from the background prediction is observed. The results are interpreted in the framework of simplified models of spin-0 dark matter mediators. For colour-neutral spin-0 mediators decaying into a pair of dark matter particles, signals with scalar mediator masses below 50 GeV in top quark final states are excluded, assuming a dark matter mass of 1 GeV and unitary coupling. For bottom quark final states 300 times the value of the production cross section for signals with scalar and pseudoscalar mediator masses between 10 and 50 GeV are excluded, assuming a dark matter mass of 1 GeV and unitary coupling. Constraints on colour-charged scalar simplified models are also presented. Assuming a dark matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding to a dark matter relic density consistent with measurements.
