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

A search for dark matter produced in association with a Higgs boson decaying to two bottom quarks has been carried out using data from 20.3 fb−1 of pp collisions at a center-of-mass energy of 8 TeV collected by the ATLAS detector at the LHC. Events with large missing transverse energy are selected....

description A search for dark matter produced in association with a Higgs boson decaying to two bottom quarks has been carried out using data from 20.3 fb−1 of pp collisions at a center-of-mass energy of 8 TeV collected by the ATLAS detector at the LHC. Events with large missing transverse energy are selected. The decay of the Higgs boson is reconstructed at low momentum with two resolved b-tagged small radius jets, and at high momentum with one large radius jet containing two b-tagged subjets. Exclusion limits are presented for the mass scales of various effective field theory operators and for the mass of the Z' mediator and tan(beta) of a Z'-2HDM simplified model that describe the interaction between dark matter particles and the Higgs boson.
