The authors report on the evidence for the decays B° → D{sub s}?− and B° → D{sub s}− K+ and the results of a search for the decays B° → D*{sub s}+?− and B° → D*{sub s}− K+ from a sample of 84 million?(4S) decays into B meson pairs collected with the BaBar detector at the PEP II asymmetric-energy e+e− collider. The measured B° → D{sub s}+?− yield has a probability of less than 10−3 to be a fluctuation of the background and they measure the branching fraction?(B° → D{sub s}+?−) = (3.2 ± 0.9(stat.) ± 1.0 (syst.)) x 10−5. The measured B° → D{sub s}− K+ yield has a probability of less than 5 x 10−4 to be a fluctuation of the background and they measure the branching fraction?(B° → D{sub s}− K+) = (3.2 ± 1.0(stat.) ± 1.0(syst.)) x 10−5. They also set 90% C.L. limits?(B° → D*{sub s}+?−)

Here, a study of the decays B0s 2![mu]+[mu]- and B0 2![mu]+[mu]- has been performed using data corresponding to an integrated luminosity of 25 fb-1 of 7 and 8 TeV proton-proton collisions collected with the ATLAS detector during the LHC Run 1. For the B0 dimuon decay, an upper limit on the branching fraction is set at B(B0 2![mu]+[mu]- )
