Περίληψη:
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
