This paper reports a search for excited electrons at the HERA electron-proton collider. In a sample corresponding to an integrated luminosity of 26 nb^(-1), no evidence was found for any resonant state decaying into e-gamma, nuW- or e-Z0. Limits on the coupling strength of an excited electron have been determined for masses between 45 and 225 GeV. This study also reports the observation of the wide-angle egamma Compton scattering process.

Abstract
This paper reports a search for excited electrons at the HERA electron-proton collider. In a sample corresponding to an integrated luminosity of 26 nb^(-1), no evidence was found for any resonant state decaying into e-gamma, nuW- or e-Z0. Limits on the coupling strength of an excited electron have been determined for masses between 45 and 225 GeV. This study also reports the observation of the wide-angle egamma Compton scattering process.File in questo prodotto:
