Title: Muon pair production in electron-proton collisions
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. To be submitted to Phys. Lett. B A. Aktas, V. Andreev, T. Anthonis, A. Asmone, A. Babaev, S. Backovic, J. Bahr, P.
