Tau Lepton Production in ep Collisions at HERA H 1 Collaboration

The production of tau leptons in ep collisions is investigated using data recorded by the H1 detector at HERA in the period 1994-2000. Tau leptons are ide ntifi d by detecting their decay products, using leptonic and hadronic decay modes. Th e cross section for the production of tau lepton pairs is measured for the first time at HE RA. Furthermore, a search… (More)
