摘要：
The analysis of events containing multiple high PT leptons (electrons and muons) produced in e(+/-) p collisions has been performed with the H1 and ZEUS detectors at HERA, using the full data sets collected by the experiments in the period 1994 - 2007. Mutually exclusive event topologies containing at least two charged leptons are analysed. The H1 and ZEUS data, corresponding to a total integrated luminosity of about 1 fb(-1), are combined in a common phase space. The observed event yields are compared to the predictions from the Standard Model. In general a good agreement is found, where the expectation is dominated by photon-photon collisions. Interesting events at high mass and high P-T are observed by both experiments. The total and differential cross sections for multi-lepton production at HERA are also measured.
