IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe present branching fraction measurements of 12 B meson decays of the form B ->(DDs(J)(*))-D-(*). The results are based on Upsilon(4S) decays in B (B) over bar pairs. One of the B mesons is fully reconstructed and the other decays to two charm mesons, of which one is reconstructed, and the mass and momentum of the other is inferred by kinematics. Combining these results with previous exclusive branching fraction measurements, we determine B(D-s(-)->phi pi(-))=(4.62 +/- 0.36(stat.)+/- 0.51(syst.))%, B(D-sJ(2460)(-)-> D-s(*-)pi(0))=(56 +/- 13(stat.)+/- 9(syst.))% and B(D-sJ(2460)(-)-> D-s(-)gamma)=(16 +/- 4(stat.)+/- 3(syst.)).

| Abstract: | We present branching fraction measurements of 12 B meson decays of the form B ->(DDs(J)(*))-D-(*). The results are based on Upsilon(4S) decays in B (B) over bar pairs. One of the B mesons is fully reconstructed and the other decays to two charm mesons, of which one is reconstructed, and the mass and momentum of the other is inferred by kinematics. Combining these results with previous exclusive branching fraction measurements, we determine B(D-s(-)->phi pi(-))=(4.62 +/- 0.36(stat.)+/- 0.51(syst.))%, B(D-sJ(2460)(-)-> D-s(*-)pi(0))=(56 +/- 13(stat.)+/- 9(syst.))% and B(D-sJ(2460)(-)-> D-s(-)gamma)=(16 +/- 4(stat.)+/- 3(syst.)). |
