Search for dark matter particles produced in association with a top quark pair at root s=13 TeV

A search is performed for dark matter particles produced in association with a top quark pair in protonproton collisions at ffiffi s p ¼ 13 TeV. The data correspond to an integrated luminosity of 35.9 fb−1 recorded by the CMS detector at the LHC. No significant excess over the standard model expec...
