Search for dark matter produced in association with a Higgs boson decaying to two bottom quarks in p−p collisions at √s= 8 TeV with the ATLAS detector.

A search for dark matter produced in association with a SM Higgs boson which decays to a pair of bottom quarks using p−p collisions at a center-of-mass energy of 8 TeV is presented. The dataset collected by the ATLAS detector at the LHC corresponds to an integrated luminosity of 20.3 fb^{−1}. The observed data are found to be consistent with the expected Standard Model backgrounds. Exclusion limits are presented for the mass scales of various effective field theory operators that describe the interaction between dark matter particles and the Higgs boson. Model-independent upper limits are also placed on the visible cross-sections for H(\rightarrow \bar{b}b)+E^{miss}_T events with E^{miss}_T above 300 GeV and 400 GeV.
