title: Explaining the anomalous CDF (mu)gamma missing- E(T) events with supersymmetry.
abstract: The CDF Collaboration recently reported an excess of events in the (mu)gamma missing E(T) (E(T)) channel that disagrees with the standard model prediction. We explain the excess via resonant smuon production with a single dominant R-parity violating coupling lambda'211, in the context of models where the gravitino is the lightest supersymmetric particle. The slepton decays to the lightest neutralino and a muon followed by neutralino decaying to a gravitino and photon. We determine a viable region of parameter space that fits the kinematical distributions of the Run I excess and illustrate the effect by examining the best fit point in detail. We provide predictions for an excess in the E(T) and photon channel at Run I and Run II.
