Multi-lepton events at HERA
Andrea Parenti
Abstract
Events containing high-PT multi-leptons were sought at HERA by the H1 and ZEUS collaborations. Experimental data were compared to simulations of γγ 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.
