Search for New Physics Using Events with Two Photons and Large Missing Transverse Energy in pp Collisions at √s = 7 TeV

Search for New Physics Using Events with Two Photons and Large Missing Transverse Energy in pp Collisions at √s = 7 TeV

A search for new physics in events with two photons and missing transverse energy is performed. Data corresponding to an integrated luminosity of 4.93 fb−1 in proton-proton collisions at √s = 7 TeV collected by the CMS detector at the Large Hadron Collider are analyzed. No excess of events with larg...
