Abstract

Cross sections for the production of two isolated muons up to high di-muon masses are measured in ep collisions at HERA with the H1 detector in a data sample corresponding to an integrated luminosity of 71 pb-1 at a centre of mass energy of √s=319 GeV. The results are in good agreement with Standard Model predictions, the dominant process being photon-photon interactions. Additional muons or electrons are searched for in events with two high transverse momentum muons using the full data sample corresponding to 114 pb-1, where data at √s=301 GeV and √s=319 GeV are combined. Both the di-lepton sample and the tri-lepton sample agree well with the predictions.
