Search for the supersymmetric partner of the top quark in dilepton events produced in proton-antiproton collisions at center of mass energy = 1.96 TeV
Abstract
We present a search for the lightest supersymmetric partner of the top quark t˜ at the Fermi National Accelerator Laboratory in proton-antiproton collisions at a center-of-mass energy [special characters omitted] = 1.96 TeV. This search was conducted within the framework of the Rp conserved Minimal Supersymmetric extension of the Standard Model, assuming the decay t˜ → l+ + [special characters omitted] + b is dominant. We searched a total Luminosity of [special characters omitted] = 1 fb−1 of data collected by the CDF experiment looking for two leptons of opposite electric charge, jets and missing transverse energy. No statistically significant evidence of the stop signal has been found in a model with degenerate sneutrino ([special characters omitted]) masses. New limits at 95% confidence level in the stop versus sneutrino mass plane have been set.
