Search for heavy long-lived particles that decay to photons at CDF II

Abstract:

We present the first search for heavy, long-lived particles that decay to photons at a hadron collider. We use a sample of Î+jet+missing transverse energy events in pp collisions at s=1.96 TeV taken with the CDF II detector. Candidate events are selected based on the arrival time of the photon at the detector. Using an integrated luminosity of 570pb-1 of collision data, we observe 2 events, consistent with the background estimate of 1.3 0.7 events. While our search strategy does not rely on m...
