Abstract The branching fraction of the decay B0sD()+sD()sB0sD()+sD()s is measured using pppp collision data corresponding to an integrated luminosity of 1.0fb11.0fb1, collected using the LHCb detector at a centre-of-mass energy of 77TeV. It is found to be B(B0sD()+sD()s)=(3.05±0.10±0.20±0.34)%, where the uncertainties are statistical, systematic, and due to the normalisation 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(B0sD±sDs)=(1.35±0.06±0.09±0.15)%,B(B0sD+sDs)=(1.27±0.08±0.10±0.14)%. All three results are the most precise determinations to date.
