CP violation in B0 -> pi+ pi- decay
T. Nakadaira
We present an improved measurement of CP-violating asymmetries in B0 -> pi+ pi- decays based on a 78/fb data sample collected at the Y(4S) resonance with the Belle detector at the…

Observation of
K. Abe, The Belle Collaboration
We report the first observation of the decay using 21.3 fb of data collected by the Belle detector at the (4S) resonance. The preliminary result for…
