| description | Single top production via flavour changing neutral currents in the reaction e/sup +/e/sup -/ to tc(u) is searched for in ~1.4fb/sup -1/ of data collected by four LEP experiments at c.m.s energies in the range 189-202 GeV. In total, 148 candidate events are selected in the data to be compared with expected background of 151.8 events. Upper limits on the single top production cross sections are derived as well as a model dependent limit Br(t to Zc) + Br(t to Zu) < 7%. |
