Measurement of the B0s→D(*)+sD(*)-s branching fractions
The branching fraction of the decay B0s→D(*)+sD(*)−s is measured using pp 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(B0s→D(*)+sD(*)−s)=(3.05±0.10±0.20±0.34)%, where the uncertainties...

| Zusammenfassung: | The branching fraction of the decay B0s→D(*)+sD(*)−s is measured using pp 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(B0s→D(*)+sD(*)−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(B0s→D*±sD∓s)=(1.35±0.06±0.09±0.15)%, B(B0s→D*+sD*−s)=(1.27±0.08±0.10±0.14)%. All three results are the most precise determinations to date. |
