Studies of B0 Decays for Measuring sin(2*beta)

TL;DR

This paper discusses how future B factories can measure the CKM angle sin(2beta) through B0 decays to CP eigenstates, using decay data from the CLEO experiment to inform these measurements.

Contribution

It highlights the potential of B0 decay channels and existing CLEO measurements for future CP violation studies in B0 mixing.

Findings

Measured CP eigenstate branching ratios relevant for sin(2beta)

Potential for observing CP asymmetry in B0 decays

Guidance for future B factory experiments

Abstract

Future asymmetric e+e- --> Upsilon(4S) B factories are being constructed to search for CP violation in B0 decays. It is hoped that a CP asymmetry may be observed in B0-B0bar mixing in analogy with that found in neutral kaons. In this mixing measurement, B0 decays to CP eigenstates, such as the rare decay B0 psi Kshort, may provide information on the CKM angle sin(2beta). I discuss decay additional CP eigenstate branching ratios measured by the CLEO experiment that may be used by future B factories to measure sin(2beta).
