A study of B meson oscillations using hadronic Z0 decays containing leptons

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

An event sample enriched in semileptonic decays of b hadrons is selected using an inclusive lepton selection from approximately 3.0 million hadronic Z0 decays collected with the OPAL detector. This sample is used to investigate B meson oscillations by reconstructing a proper decay time for the parent of each lepton, using a jet charge method to estimate the production flavour of this parent, and using the lepton charge to tag the decay flavour. We measure the mass difference between the two B0 d mass eigenstates
