Search for new physics with photons at the tevatron

Abstract

We report on a search for compositeness in eeγ events and a search for gauge-mediated supersymmetry in γγ E/T events. We also report on two signature-based searches for anomalous production of γγ + X (where X = e,μ,γ,E/T) and γl + X (where X = E/T l, γ). The analyses are based on 0.9-1.2 fb-1 of data from pp̄ collisions at s√ = 1.96 TeV collected with the CDF and D0 detectors at the Fermilab Tevatron. No significant excess of data over the predicted background has been observed.
