Measurement of the Branching Fraction $\it{B}\it{(\Lambda_c^{+} -> p K^{-}\pi^{+}})$

A. Zupanc, C. Bartel, K. Belous, R Mussa et autres

We present the first model-independent measurement of the absolute branching fraction of the Lambda_c+ -> p K- pi+ decay using a data sample of 978 fb^-1 collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The number of Lambda_c+ baryons …

Observation of D_s1(2536)^+ → D^+π^-K^+ and angular decomposition of D_s1(2536)^+ →D^*+K_S^0

V. Balagura, I. Adachi, H. Aihara, K. Arinstein et autres

Using 462 fb^{-1} of e^+e^- annihilation data recorded by the Belle detector, we report the first observation of the decay D_s1(2536)^+ → D+π^-K^+. The ratio of branching fractions \frac{B(D_s1(2536)^+ → D^+π^- K^+}{B(D_s1(2536)^+ → D+K^0}is measured to be (3.27±0.18±0.37)%. We also study the …

Time-Dependent CP-Violating Asymmetry in B^0→p^0γ Decays

Y. Ushiroda, K. Sumisawa, N. Taniguchi, I. Adachi et autres

We report the first measurement of CP-violation parameters in B^0 → p^0γ decays based on a data sample of 657×10^6B\bar{B} pairs collected with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. We obtain the time-dependent and direct CP-violating parameters, S_p0γ=-0.83±0.65(stat)±0.18(syst) and …
