Bounds on the electromagnetic interactions of excited spin-3/2 leptons
R. Walsh, A. J. Ramalho
Abstract
We discuss possible deviations from QED produced by a virtual excited spin-3/2 lepton in the reaction e+e- 2γ. Data recorded by the OPAL Collaboration at a c.m. energy s = 183 GeV are used to establish bounds on the nonstandard-lepton mass and coupling strengths.
