We present the results of the first hadron collider search for heavy, long-lived neutralinos that decay via e χ 0 1 → γ e G in gauge-mediated supersymmetry breaking models. Using an integrated lumi-nosity of 570±34 pb −1 of p¯ p collisions at √ s = 1.96 TeV, we select γ+jet+missing transverse energy candidate events based on the arrival time of a(More)
We investigate the impact of noise on a two-dimensional simple paradigmatic piecewise-smooth dynamical system. For that purpose, we consider the motion of a particle subjected to dry friction and colored noise. The finite correlation time of the noise provides an additional dimension in phase space, causes a nontrivial probability current, and establishes a(More)
