Search for supersymmetry in events with a lepton, a photon, and large missing transverse energy in pp collisions at root s=7 TeV

A search is performed for an excess of events, over the standard model expectations, with a photon, a lepton, and large missing transverse energy in pp collisions at Ös = 7TeV. Such events are expected in many new physics models, in particular a supersymmetric theory that is broken via a gauge-media...
