Search for New Physics with Photons at the Tevatron

TL;DR

This paper reports on multiple searches for new physics phenomena involving photons at the Tevatron collider, using data from the CDF and D0 detectors, but finds no significant deviations from the Standard Model predictions.

Contribution

It presents comprehensive searches for compositeness, supersymmetry, and anomalous photon-related events using Tevatron data, expanding the scope of experimental tests for new physics.

Findings

No significant excess observed over background predictions.

Constraints set on models of compositeness and supersymmetry.

Enhanced understanding of photon-related event signatures at Tevatron.

Abstract

We report on a search for compositeness in ee+gamma events and a search for gauge-mediated supersymmetry in gamma+gamma+met events. We also report on two signature-based searches for anomalous production of gamma + gamma + X (where X=e, mu, gamma, met) and gamma + lepton + X. The analyses are based on 0.9--1.2 fb-1 of data from p-pbar collisions at sqrt(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.
