Abstract

Results of a search for new phenomena in events with an energetic photon and large missing transversemomentum with the ATLAS experiment at the LHC are reported. Data were collected in proton-protoncollisions at a center-of-mass energy of 8 TeVand correspond to an integrated luminosity of20.3fb−1. Theobserved data are well described by the expected Standard Model backgrounds. The expected (observed)upper limit on the fiducial cross section for the production of events with a photon and large missingtransverse momentum is 6.1 (5.3) fb at 95% confidence level. Exclusion limits are presented on models ofnew phenomena with large extra spatial dimensions, supersymmetric quarks, and direct pair production ofdark-matter candidate
