Title: Studies of $B^0$ Decays for Measuring $\sin(2\beta)$

Abstract: Future asymmetric $e^{+}e^{-} \rightarrow \Upsilon$(4S) $B$ factoriesare being constructed to search for CP violation in $B^0$ decays. It is hoped that a CP asymmetry may be observed in $B^0\mbox{--}\overline{B}^0$ mixing in analogy with that found in neutral kaons. In this mixing measurement, $B^0$ decays to CP eigenstates, such as the rare decay $B^0 \rightarrow \psi K_S$, may provide information on the CKM angle $\sin(2\beta)$. I discuss decay additional CP eigenstate branching ratios measured by the CLEO experiment that may be used by future $B$ factories to measure $\sin(2\beta)$.
