Search for displaced muonic lepton jets from light Higgs boson decay in proton–proton collisions at √s = 7 TeV with the ATLAS detector

A search is performed for collimated muon pairs displaced from the primary vertex produced in the decay of long-lived neutral particles in proton–proton collisions at √s = 7 TeV centre-of-mass energy, with the ATLAS detector at the LHC. In a 1.9 fb<sup>−1</sup> event sample collected dur...

description A search is performed for collimated muon pairs displaced from the primary vertex produced in the decay of long-lived neutral particles in proton–proton collisions at √s = 7 TeV centre-of-mass energy, with the ATLAS detector at the LHC. In a 1.9 fb<sup>−1</sup> event sample collected during 2011, the observed data are consistent with the Standard Model background expectations. Limits on the product of the production cross section and the branching ratio of a Higgs boson decaying to hidden-sector neutral long-lived particles are derived as a function of the particles’ mean lifetime.
