Multi-lepton events at HERA

High Energy Physics - Experiment 2007-05-23 v1

Abstract

Events containing high-PTP_T multi-leptons were sought at HERA by the H1 and ZEUS collaborations. Experimental data were compared to simulations of γγl+l\gamma \gamma \to l^+ l^- processes, and H1 extracted the total and differential cross sections of the processes. The doubly-charged Higgs, which decays into lepton pairs, was analysed by H1 as a possible source of the multi-electron events, which have been observed at high invariant masses.
