A search for single-top production, ep -> et X, has been performed with the ZEUS detector at HERA using data corresponding to an integrated luminosity of 0.37 fb(-1). No evidence for top production was found, consistent with the expectation from the Standard Model. Limits were computed for single-top production via flavour changing neutral current transitions involving a neutral electroweak vector boson, gamma or Z. The result was combined with a previous ZEUS result yielding a total luminosity of 0.50 fb(-1).

Abstract

A search for single-top production, ep -> et X, has been performed with the ZEUS detector at HERA using data corresponding to an integrated luminosity of 0.37 fb(-1). No evidence for top production was found, consistent with the expectation from the Standard Model. Limits were computed for single-top production via flavour changing neutral current transitions involving a neutral electroweak vector boson, gamma or Z. The result was combined with a previous ZEUS result yielding a total luminosity of 0.50 fb(-1).
