الوصف: A search for single-top production, $ep \rightarrow etX$, has been performed with the ZEUS detector at HERA using data corresponding to an integrated luminosity of $0.37\fbi$. 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. The result was combined with a previous ZEUS result yielding a total luminosity of 0.50fb-1. A 95% credibility level upper limit of 0.13 pb was obtained for the cross section at the centre-of-mass energy of $\sqrt{s}=315\gev$.
Comment: Included approximate NLO and NNLO corrections to the cross section calculation used to derive coupling limit for the top production mediated by gamma exchange. 30 pages, 5 figures, 3 tables. Published in Phys. Lett. B 708 (2012) 27
