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

Abstract

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