Bounds on the electromagnetic interactions of excited spin-3/2 leptons

High Energy Physics - Phenomenology 2009-10-31 v1

Abstract

We discuss possible deviations from QED produced by a virtual excited spin-3/2 lepton in the reaction e+e2γe^+e^- \longrightarrow 2\gamma. Data recorded by the OPAL Collaboration at a c.m. energy s=183GeV\sqrt{s} = 183 GeV are used to establish bounds on the nonstandard-lepton mass and coupling strengths.
