HERA high $Q^{2}$ events as indications of excited leptons with weak isotopic spin 3/2

Abstract

The H1 and ZEUS anomalous events are interpreted as being due to the production and the decay of excited leptons $E$ , which correspond to spin 1/2 resonances of the first generation lepton doublet ( $ν_{e}, e$ ) with W triplet. This assumption is supported by considering of Bethe-Salpeter equation in the ladder approximation with anomalous triple gauge boson vertex. The solution with weak isospin $I = 3/2$ is shown to exist for zero mass state, that means M_E $i ss ma l l in co m p a r i so n w i t h T e V ma sssc a l e . T h eco u pl in g o f$ E $w i t h l e pt o n s an d$ W $i s d e f in e d b y t h e n or ma l i z a t i o n co n d i t i o n .

Isotopic relations for different channels are presented as a tool for checking the interpretation.
