Color-suppressed decays of $B$ mesons to final states with $\psi(2S)$ mesons have been observed with the CLEO detector. The branching fractions for the decays $B^+ \to \psi(2S) K^+$, $B^+ \to \psi(2S) K^*(892)^+$, $B^0 \to \psi(2S) K^0$,…
The measurement of $\sin {2\beta}$ from $B_d \to J/\psi K_s$ does not resolve the discrete ambiguities in the angle $\beta$. A measurement of $\cos {2\beta}$ is therefore desirable.This talk is about measuring the CKM angle $\beta(\phi_1)$…

We report the first observation of a number of decay modes of the B meson, namely $B^0 \to D^{*-} (5\pi)^+$, $B^+ \to D^{*-} (4\pi)^{++}$ and $B^+ \to \bar{D}^{*0} (5\pi)^+$, where $(n\pi)$ implies the combination of n charged pions. The…
