Isolated Leptons, W and Single Top at HERA

Nick Malden

Standard Model W production in ep collisions is characterised by a high pT isolated lepton and missing overall pT in the leptonic decay channel and three high pT jets in the hadronic decay channel. These topologies are also the final state of single top production via a FCNC \kappa tu\gamma vertex. Results of searches for these topologies are presented and consequent upper limits on the \kappa tu\gamma coupling are derived.
