The data used correspond to an integrated luminosity of 3.0 fb(-1) of proton-proton collisions. The ratios of branching fractions are B(B-s(0) -> D-s(-/+) K--/+)/B(B-s(0) -> D-s(-)pi(+)) = 0.0752 +/- 0.0015 +/- 0.0019 and B(B-0 -> Ds-K+)/B(B-0 -> D-pi(+)) = 0.0129 +/- 0.0005 +/- 0.0008, where the uncertainties are statistical and systematic, respectively. %K Hadron-Hadron Scattering %K Branching fraction %K B physics %K Flavor physics %R 10.1007/JHEP05(2015)019 %U http://arxiv.org/abs/1412.7654 %U https://doi.org/10.1007/JHEP05(2015)019 %P 019-16pp
