چکیده
We report measurements of the branching fractions and $CP$ asymmetries for $D_s^{+} \rightarrow K^{+} \eta $, \pi^0 \pi^{+} $ decays, fraction \pi^0$. Our results are based on a data sample corresponding to an integrated luminosity 921 fb$^{-1}$ collected by Belle detector at KEKB $e^+e^-$ asymmetric-energy collider. in these decays most precise to-date; no evidence violation is found.

متن کاملMeasurement of branching fractions and charge asymmetries for exclusive B decays to charmonium.
We report measurements of branching fractions and charge asymmetries of exclusive decays of neutral and charged B mesons into two-body final states containing a charmonium state and a light strange meson. The charmonium mesons considered are J/psi, psi(2S) and chi(c1), and the light meson is either K or K(*). We use a sample of about 124x10(6) BB pairs collected with the BABAR detector at the P...

Measurement of CP Asymmetries and Branching Fractions in B → ππ and B →
We present preliminary measurements of the CP asymmetries and branching fractions for B → ππ and B → Kπ decays. A total of 347 million BB events collected by the BABAR detector at the PEP-II asymmetric-energy e+e− collider at SLAC are used for these results. We find Sππ = −0.53 ± 0.14 ± 0.02 Cππ = −0.16 ± 0.11 ± 0.03 AKπ = −0.108 ± 0.024 ± 0.008 B(B0 → ππ) = (1.48 ± 0.26± 0.12) × 10−6 B(B± → π±...
