The branching fraction and CP asymmetry are measured to be $ B(B+→D+sϕ)=(1.87+1.25−0.73(stat)±0.19(syst)±0.32(norm))×10−6,ACP(B+→D+sϕ)=−0.01±0.41(stat)±0.03(syst). $ The last uncertainty on B(B+→D+sϕ) is from the branching fractions of the B+→D+sD¯¯¯0 normalization mode and intermediate resonance decays. Upper limits are also set for the branching fractions of the related decay modes B+(c)→D+(s)K∗0,B+(c)→D+(s)K¯¯¯∗0 and B+c→D+sϕ , including the result B(B+→D+K∗0)<1.8×10−6 at the 90% credibility level.17 p.application/pdfengcc by, (c) LHCb Collaboration, 2013http://creativecommons.org/licenses/by/3.0/Interaccions d'hadronsHadronsFísica nuclearDetectors de radiacióHadron interactionsHadronsNuclear physicsNuclear countersFirst evidence for the annihilation decay mode B+→D+sϕinfo:eu-repo/semantics/article6196392014-07-29info:eu-repo/semantics/openAccess
