Search for events with an isolated lepton and missing transverse momentum and a measurement of W production at HERA
Abstract
A search for events with an isolated high-energy lepton and large missing transverse momentum has been performed with the ZEUS detector at HERA using a total integrated luminosity of 504 pb-1. The results agree well with Standard Model predictions. The cross section for production of single W bosons in electron-proton collisions with unpolarised electrons is measured to be 0.89+0.25-0.22 (stat.) 0.10 (syst.) pb.
