Search for New Physics in Lepton + Photon + X Events with 929 pb-1 of ppbar Collisions at roots = 1.96 TeV (result for the summer'2006 conferences)

Abstract

We present results of a search in 929 pb-1 of ppbar collisions at 1.96 TeV for the anomalous production of events containing a charged lepton (electron or muon) and a photon, both with high transverse momentum, accompanied by additional signatures, X, including missing transverse energy and additional leptons and photons. We use the same selection criteria as in the previous CDF Run I search, but with an order-magnitude larger data set, a higher ppbar collision energy, and the CDF II detector.
