Limits on Extra Dimensions and New Particle Production in the Exclusive Photon and Missing Energy Signature in p pbar Collisions at sqrt(s) = 1.8 TeV
Abstract
The exclusive gamma-met signal has a small standard model cross-section and is thus a good channel in which to look for signs of new physics. This signature is predicted by models with a superlight gravitino or with large extra spatial dimensions. We search for such signals at the CDF detector at the Tevatron, using 87 pb-1 of data at sqrt(s) = 1.8 TeV, and extract 95% C.L. limits on these processes. A limit of 221 GeV is set on the scale |F|1/2 in supersymmetry models. For 4, 6, and 8 extra dimensions, limits on the fundamental mass scale MD of 549, 581, and 602 GeV, respectively, are found. We also specify a `pseudo-model-independent' method of comparing the results to theoretical predictions.
