Abstract

A search fur events with one jet and at most one isolated lepton used data taken at LEP-2 by the DELPHI detector. These data were accumulated at a center-of-mass energy of 183 GeV and correspond to an integrated luminosity of 47.7 pb(-1) Production of single scalar and vector leptoquarks was searched for. Limits at 95% confidence level were derived on the masses (ranging from 134GcV/c(2) to 171GeV/c(2) for electromagnetic type couplings) and couplings of the leptoquark rates. A search for top-charm flavour changing neutral currents (e(+)e(-) --> (t) over bar c or charge conjugate) used the semileptonic decay channel. A limit on the flavour changing cross-section via neutral currents was set at 0.55pb (95%: confidence level). (C) 1999 Elsevier Science B.V. All rights reserved.
