Abstract
Multi-electron and multi-muon production at high transverse momentum is measured in scattering at HERA. Previous published analyses are extended, combining new HERA II data taken in 2003-2004 with previous HERA I data sample. In addition events with high electrons and muons are investigated here for the first time. Yields of di-lepton and tri-lepton events are measured and a general good agreement is found with the Standard Model prediction, dominated by photon-photon interactions. Events are observed with leptons of high transverse momenta in a domain where the Standard Model prediction is low.
