Combination of Searches for Invisible Higgs Boson Decays with the ATLAS Experiment Aaboud, M. Aguilar Saavedra, Juan Antonio Atlas Collaboration Dark matter particles, if sufficiently light, may be produced in decays of the Higgs boson. This Letter presents a statistical combination of searches for H → invisible decays where H is produced according to the standard model via vector boson fusion, ZðllÞH, and W=ZðhadÞH, all performed with the ATLAS detector using 36.1 fb−1 of pp collisions at a center-of-mass energy of ffiffiffi s p ¼ 13 TeV at the LHC. In combination with the results at ffiffiffi s p ¼ 7 and 8 TeV, an exclusion limit on the H → invisible branching ratio of 0.26ð0.17 þ0.07 −0.05 Þ at 95% confidence level is observed (expected). 2019-10-17T07:30:35Z 2019-10-17T07:30:35Z 2019-06-13 journal article Aaboud, Morad, et al.
