Possible Implications of Small or Large CP Violation in Bd0 vs Bd0→J/ψKS Decays

  • We argue that a small or large CP-violating asymmetry AψKS in B0d vs B0d→J/ψKS decays,which seems to be favored by the recent BaBar or Belle data,might hint at the existence of new physics in B0d-B0d mixing. We present a model-independent framework to show how new physics modifies the standard-model CP-violating asymmetry A SM ψKS. We particularly emphasize that an experimental confirmation of AψKS≈A SM ψKS must not imply the absence of new physics in B0d-B0d mixing.

Possible Implications of Small or Large CP Violation in Bd0 vs Bd0→J/ψKS Decays

Abstract: We argue that a small or large CP-violating asymmetry AψKS in B0d vs B0d→J/ψKS decays,which seems to be favored by the recent BaBar or Belle data,might hint at the existence of new physics in B0d-B0d mixing. We present a model-independent framework to show how new physics modifies the standard-model CP-violating asymmetry A SM ψKS. We particularly emphasize that an experimental confirmation of AψKS≈A SM ψKS must not imply the absence of new physics in B0d-B0d mixing.
