The $B_s \to D_s^{(*)\pm} K^\mp$ decays allow a theoretically clean determination of $\phi_s+\gamma$, where $\phi_s$ is the $B^0_s$-$\bar B^0_s$ mixing phase and $\gamma$ the usual angle of the unitarity triangle. A sizable $B_s$ decay…

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…

We propose a new method to extract $D^0-\bar{D}^0$ mixing parameters using the $D^0 \to \bar{K}{}^0 \pi^0$ decay with the $\bar{K}{}^0$ reconstructed in the semileptonic mode. Although a $K^0 \to \pi^\pm l^\mp \nu_l$ decay suffers from low…
