Measurement of the B0s→Ds()+Ds()− branching fractions

Abstract

The branching fraction of the decay B 0 s → D ( * ) + s D ( * ) − s is measured using p p collision data corresponding to an integrated luminosity of 1.0

fb − 1 , collected using the LHCb detector at a center-of-mass energy of 7 TeV. It is found to be B ( B 0 s → D ( * ) + s D ( * ) − s ) = ( 3.05 ± 0.10 ± 0.20 ± 0.34 ) % , where the uncertainties are statistical, systematic, and due to the normalization channel, respectively. The branching fractions of the individual decays corresponding to the presence of one or two D * ± s are also measured. The individual branching fractions are found to be B ( B 0 s → D * ± s D ∓ s ) = ( 1.35 ± 0.06 ± 0.09 ± 0.15 ) % , B ( B 0 s → D * + s D * − s ) = ( 1.27 ± 0.08 ± 0.10 ± 0.14 ) % . All three results are the most precise determinations to date.
