We present the results of searches for non-standard model phenomena in photon final states. These searches use data from integrated luminosities of (almost equal to) 1-4 fb−1 of p{bar p} collisions at (square root)s = 1.96 TeV, collected with the CDF and D0 detectors at the Fermilab Tevatron. No significant excess in data has been observed. We report limits on the parameters of several BSM models (excluding SUSY) for events containing photons.

Many extensions have been proposed to the Standard Model of fundamental particles and interactions, therefore we have conducted a general search with the Collider Detector at Fermilab (CDF) for particles which would be expected to appear as a resonance in the b$\bar{b}$ mass spectrum produced in proton-antiproton collisions at a center-of-mass energy of √s = 1.8 TeV at the Fermilab Tevatron collider.

The CDF detector has accumulated a large data sample of p{bar p} collisions at {radical}s = 1.96 TeV at the Fermilab Tevatron. In this report we present the results of searches for physics beyond the Standard Model using final states of 2 leptons or 2 photons using 190 pb{sup -1} to 448 pb{sup -1} of data. No deviation from the predictions of Standard Model was observed. The non-observation was used to derive cross section limits on contributions to these final states from possible new physics processes. For many specific new physics models, such as Z', Randall-Sundrum Graviton, Large Extra Dimensions and SUSY, these cross section limits can be used to place strong constraints on their parameters.

Tevatron Experiments: CDF and 6 D0 collected during October 1992 and February 1996 (Run I) a data sample of roughly 120 pb−1 p {bar p} collisions at a center of mass energy (square root)s = 1.8 TeV. A large variety of physical studies have been performed using these data. Current paper reviews last results obtained searching for physics beyond the Standard Model. Direct Supersymmetry (SUSY) searches are not part of this review.

We present a variety of model-independent studies of final states involving photons in combination with other objects. These include charged leptons (including taus), jets (including b-tagged jets), additional photons, and missing energy. Several kinematic distributions are examined in each final state considered to search for discrepancies from the standard model. One of the final states examined, involving a photon, a charged lepton, a b-tagged jet, and missing energy, is employed to study standard model production of t-tbar-gamma in addition to potential new physics. The results use data collected at the Tevatron.

This first open access volume of the handbook series contains articles on the standard model of particle physics, both from the theoretical and experimental perspective. It also covers related topics, such as heavy-ion physics, neutrino physics and searches for new physics beyond the standard model. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access
