Single top quark production via four-fermion contact interactions associated to flavour-changing neutral currents was searched for in data taken by the DELPHI de- tector at LEP2. The data were accumulated at centre-of- mass energies ranging from 189 to 209 GeV, with an in- tegrated luminosity of 598.1 pb−1. No evidence for a sig- nal was found. Limits on the energy scale Λ, were set for scalar-, vector- and tensor-like coupling scenarios.

Abstract

The data were accumulated at centre-of- mass energies ranging from 189 to 209 GeV, with an in- tegrated luminosity of 598.1 pb−1. No evidence for a sig- nal was found. Limits on the energy scale Λ, were set for scalar-, vector- and tensor-like coupling scenarios.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
