Abstract

A search for the leptonic decays of W bosons produced in the reaction e/sup +/p to e/sup +/W/sup +or-/X at a centre-of-mass energy of 300 GeV has been performed with the ZEUS detector at HERA using an integrated luminosity of 47.7 pb/sup -1/. Three events consistent with W to e nu decay are found, giving a cross section estimate of 0.9/sub -0.7//sup +1.0/+or-0.2 pb, in good agreement with the standard model prediction. The corresponding 95% C.L. upper limit on the cross section is 3.3 pb. A search for the decay W to mu nu has a smaller selection efficiency and yields no candidate events. Limits on the cross section for W production with large hadronic transverse momentum have been obtained. A search for high-transverse-momentum isolated tracks in events with large missing transverse momentum yields results in good agreement with standard model expectations, in contrast to a recent report by the H1 collaboration of the observation of an excess of such events.
