We consider the semileptonic and nonleptonic $D_s$ decay modes to final states with $\eta$ and $\eta^\prime$. We use QCD sum rules to determine the $D_s \to \eta$ form factor $f_+^\eta$, and a generalized factorization ansatz to compute…

Phenomenological expressions are derived for rates of the $\Delta (1232)$ radiative and Dalitz decays, $\Delta (1232)$ $\to N\gamma$ and $\Delta (1232)$ $\to Ne^{+}e^{-}$. Earlier calculations of these decays are commented.

Using the BaBar measurements of the Dalitz plots for the decays $B^0 \to K^+\pi^0\pi^-$, $B^0 \to K^0\pi^+\pi^-$, $B^+ \to K^+\pi^+\pi^-$, $B^0 \to K^+ K^0 K^-$, and $B^0 \to K^0 K^0 \bar K^0$, we demonstrate that it is possible to cleanly…

We propose a phenomenological three component model describing the decay amplitude of the process $D_{s}^{+} \ra 3\pi$. The first component is a constant background, the second one is a Breit-Wigner amplitude associated to a quasi two-body…
