摘要：

The latest HERA results on searches for events with high-P-T leptons in ep collisions axe presented. The full HERA I data set, corresponding to 115 pb(-1) (HI) and 130 pb(-1) (ZEUS), is used. Searches for TV production and for signatures of new physics including single top production via flavor changing neutral currents have been performed in events with high-P-T leptons and missing transverse momentum. The production of multi-lepton events at high transverse momenta has been studied. Some 2- and 3-electron events are observed at high di-electron masses, for which the Standard Model expectation is low. A possible interpretation in terms of doubly charged Higgs boson production is ruled out.
