| Abstract |
A search for events with a high energy isolated electron or muon and
missing transverse momentum has been performed at the electron-proton
collider HERA. Within the Standard Model such events are expected to be
mainly due to W boson production with subsequent leptonic decay. The
analysis of the former data collected in the period 1994-2000 (HERA I)
and corresponding to an integrated luminosity of 118.3 pb-1 revealed an
excess of events with transverse momentum of the hadronic system greater
than 25 GeV. This paper presents results obtained using recent
data colected in the period 2003-2005 (HERA II) in electron- and
positron-proton collisions. |
