| Abstract |
Events with two or more leptons (electrons or muons) with high
transverse momentum are measured in electron-proton collisions at HERA
using the data sample collected in the period 1994-2005. The electrons
and muons are selected in a similar phase space and classes of events
containing various combinations of two or three leptons are studied (ee,
eee, emu, mumu, emumu, etc.).
Within the Standard Model such events are mainly produced via
photon-photon collisions.
Using the same data sample, a general search for new physics at large
transverse momentum is performed. |
