We present results of a search for CP violation in B0-B¯0 mixing with the BABAR detector.

Abstract
We present results of a search for CP violation in B0-B¯0 mixing with the BABAR detector. We select a sample of B0→D*-Xℓ+ν decays with a partial reconstruction method and use kaon tagging to assess the flavor of the other B meson in the event. We determine the CP violating asymmetry ACP≡[N(B0B0)-N(B¯0B¯0)]/[N(B0B0)+N(B¯0B¯0)]=(0.06±0.17-0.32+0.38)%, corresponding to ΔCP=1-|q/p|=(0.29±0.84-1.61+1.88)×10-3.File in questo prodotto:
