Evidence for CP violation in the decay D+ →KS0π+
We observe evidence for CP violation in the decay D +→ KS0π + using a data sample with an integrated luminosity of 977fb -1 collected by the Belle detector at the KEKB e +e - asymmetric-energy collider. The CP asymmetry in the decay is measured to be (-0.363±0.094±0.067)%, which is 3.2 standard deviations away from zero, and is consistent with the expected CP violation due to the neutral kaon in the final state. © 2012 American Physical Society.
