Title: Search for new physics with photons at CDF

Abstract

The authors present searches for signals of new physics beyond the Standard Model. The focus of this paper is on the results obtained with photons in the final state. they report on two model-independent searches for anomalous production of {gamma}{gamma} + X (where X = e, {mu}, {gamma}, E{sub T}) and {gamma}l + X (where l = e, {mu} and X = l, {gamma}, E{sub T}) events and one novel search for delayed photons. The analyses are based on {approx} 1 fb{sup -1} of data and significantly update earlier results. No significant excess of data over the predicted background is observed. They report kinematic distributions, data and background counts.

  • A global, model-independent search for high-pT exotic phenomena is presented using 927 pb{sup -1} of CDF II data. The search algorithms employed in this analysis are Vista and Sleuth. These proceedings focus on Vista, including a description of the method and a summary of results.
  • A brief review of searches for physics beyond the Standard Model with photons using the CDF detector at the Tevatron is given here. These include searches for supersymmetry, extra dimensions, excited electrons and W/Z+{gamma} production, as well as anomalous photon production. Recent results from CDF Run II experiment are presented, but some results from Run I are also reviewed.
  • 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 Dimensionsmore » and SUSY, these cross section limits can be used to place strong constraints on their parameters.« less
  • These proceedings describe Sleuth, a quasi-model-independent search strategy targeting new electroweak scale physics, and its application to 927 pb{sup -1} of CDF II data. Exclusive final states are analyzed for an excess of data beyond the Standard Model prediction at large summed scalar transverse momentum. This analysis of high-pT data represents one of the most encompassing searches so far conducted for new physics at the energy frontier.
