Cp Asymmetry

  title={Cp Asymmetry},
  author={Maurizio Pierini and Luca Silvestrini},
Performing a fit to the available experimental data, we quantify the effect of long-distance contributions from penguin contractions in B0 → J/ψK0 decays. We estimate the deviation of the measured SCP term of the time-dependent CP asymmetry from sin 2β induced by these contributions and by the penguin operators. We find ∆S = 0.000±0.017 ([−0.035, 0.033… CONTINUE READING
