Abstract

Many new physics models predict mechanisms that could produce a photon and jets signature. We search in the photon + jets channel, independent of any model, for new physics using CDF Run II data collected at the Fermilab Tevatron from p-pbar collisions at a center of mass energy of 1.96 TeV. A variety of techniques are applied to estimate the standard model expectation and non-collision backgrounds. We examine several kinematic distributions including transverse energy of the photon and invariant masses for discrepancies with the standard model.
