  title={Search for single-top production in ep collisions at HERA},
  author={Zeus Collaboration},

}
A search for single-top production, ep → etX, 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 avour changing neutral current transitions. The result was combined with a previous ZEUS result yielding a total luminosity of 0.50 fb−1. A 95% credibility level upper limit of 0.13 pb… Expand
