Strong two-meson decays of light and charmed vector mesons

Roberto Correa da Silveira, Fernando E. Serna, Bruno El-Bennich

We calculate the strong decay couplings for $\rho \to \pi \pi$, $\varphi \to KK$, $K^{\ast }\to K\pi$ and $D^{\ast }\to D\pi$ in a unified and consistent approach based on the impulse approximation, nonperturbat…
