Abstract

The Run I results on the searches for new physics in photon final states were intriguing. The rare eeγγ≠E_T candidate event and the measured event rate for the signature ℓ+γ+≠E_T, which was 2.7 sigma above the Standard Model predictions, sparked signature-based searches in the γγ+X and ℓγ+X channels. With more data in Run II we should be able to answer a simple question: was it an anomaly or were the Run I results the first evidence for new physics? We present searches for new physics in photon final states at CDF Run II, Fermilab, with substantially more data and a higher p̄p collision energy, 1.96 TeV, and the upgraded CDF-II detector.
