Measurement of the B ° lifetime OPAL

Abstract

The hfetlme of the B ° meson has been measured with the OPAL detector at LEP A sample of B ° (~s) decays has been obtained using D s g+ (and charge conjugate, where g denotes a lepton) combinations, where the D s was reconstructed in e~ther the q~n-or K*°K-channel The decay lengths of D~-g + combinations were measured using vertex reconstructmn Proper decay… (More)
