We report a search for the charmless hadronic decay B0 -> \eta \pi^0 with a data sample corresponding to an integrated luminosity of 694 fb^{-1} containing 753\times 10^6 B\bar{B} pairs. The data were collected by the Belle experiment running on the \Upsilon(4S) …

We present an improved measurement of $\mathrm{CP}$-violating asymmetries in ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ decays based on a $78{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. We reconstruct one neutral B meson as a ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ $\mathrm{CP}$ …
