Combined fits to the supersymmetric explanation of anomalous lepton-gamma-missing E-T events

摘要

The CDF experiment reported a lepton-photon missing transverse energy (is not an element of(T)) signal 3sigma in excess of the Standard Model prediction in Tevatron Run I data. The excess can be explained by the resonant production of a smuon, which subsequently decays to a muon, a photon and a gravitino. Here, we perform combined fits of this model to the CDF gammalis not an element of(T) excess, the DO measurement of the same channel and the CDF gammais not an element of(T) channel. Although the rates of the latter two analyses are in agreement with the Standard Model prediction, our model is in good agreement with these data because their signal to background efficiency is low at the best-fit point. However, they help to constrain the model away from the best-fit point. (C) 2002 Elsevier Science B.V. All rights reserved. References: 26
