Abstract

We present results of a search for anomalous production of events containing a charged lepton (ℓ, either e or μ) and a photon (γ), both with high transverse momentum, accompanied by additional signatures X, including missing transverse energy (E̸T) and additional leptons and photons. We use the same selection criteria as in a previous CDF search but with a substantially larger data set, 305 pb-1, a pp̅ collision energy of 1.96 TeV, and the CDF II detector. We find 42 ℓγE̸T events versus an expectation of 37.3±5.4 events. We observe 31 ℓℓγ+X events versus an expectation of 23.0±2.7 events. We find no events similar to the run I eeγγE̸T event.
