In a recently suggested method for measuring the weak phase $\gamma$ in $B^\pm \to K^\pm (KK^*)_D$ decays, the relative strong phase $\delta_D$ in $D^0 \to K^{*+} K^-$ and $D^0 \to K^{*-} K^+$ decays (equivalently, in $D^0 \to K^{*+} K^-$…
Based on 2.92 fb$^{-1}$ of $e^+e^-$ collision data collected with the BESIII detector at $\sqrt{s}$ = 3.773 GeV, we measured the asymmetry $\mathcal{A}_{CP\to K\pi}$ of the branching fractions of $D^{CP\pm}\to K^-\pi^+$ ($D^{CP\pm}$ are the…

Besides the conventional strong and electromagnetic decay modes, the $J/{\psi}$ particle can also decay via the weak interaction in the standard model. In this paper, nonleptonic $J/{\psi}$ ${\to}$ $D_{s,d}{\pi}$, $D_{s,d}K$ weak decays,…

The processes $D^0\to K^0 K^-\pi^+$ and $D^0\to\ok K^+\pi^-$ involve intermediate vector resonances whose amplitudes and phases are related to each other via flavor SU(3) symmetry. A closer look at Dalitz plots for these two processes is…

We report a study of the decay $B^0\rightarrow D K^+\pi^-$ followed by $D\rightarrow K^-\pi^+$, where $D$ indicates $D^0$ or $\bar{D}^0$. We reconstruct the $D K^+\pi^-$ state in a phase space corresponding to $D K^{*}(892)^0$. The…
$\bar B \to D\pi$, $D^*\pi$, $J/\psi\bar K$ and $J/\psi\pi$ decays are studied. Their amplitude is given by a sum of factorized and non-factorizable ones. The latter which is estimated by using a hard pion approximation is rather small in…
