I am looking for the theoretical value of [itex]sin(2\beta)[/itex] but I just keep finding the experimental one. I supose there is a theoretical value because I have read that they choose in the BaBar experience the channel [itex]B^0\rightarrow J/\psi K^0_S[/itex] because the theoretical error for [itex]sin(2\beta)[/itex] was very small...(adsbygoogle = window.adsbygoogle || []).push({});

Thanks for your replies.
