We present results of a search at CDF in 929 +/- 56 pb(-1) of p (p) over bar collisions at 1.96 TeV for the anomalous production of events containing a high-transverse momentum charged lepton (l, either e or mu) and photon (gamma), accompanied by missing transverse energy (MET), and/or additional leptons and photons, and jets (X). We use the same selection criteria as in a previous CDF Run I search, but with an order-magnitude larger data set, a higher p (p) over bar collision energy, and the CDF II detector. We find 163 l gamma MET + X events, compared to an expectation of 150.6 +/- 13.0 events. We observe 74 ll gamma + X events, compared to an expectation of 65.1 +/- 7.7 events. We find no events similar to the Run I ee gamma gamma MET event.

Abstract

We present results of a search at CDF in 929 +/- 56 pb(-1) of p (p) over bar collisions at 1.96 TeV for the anomalous production of events containing a high-transverse momentum charged lepton (l, either e or mu) and photon (gamma), accompanied by missing transverse energy (MET), and/or additional leptons and photons, and jets (X). We use the same selection criteria as in a previous CDF Run I search, but with an order-magnitude larger data set, a higher p (p) over bar collision energy, and the CDF II detector. We find 163 l gamma MET + X events, compared to an expectation of 150.6 +/- 13.0 events. We observe 74 ll gamma + X events, compared to an expectation of 65.1 +/- 7.7 events. We find no events similar to the Run I ee gamma gamma MET event.
