Abstract

Simulation methods for the decays $B \to {\pi}^+ {\pi}^- V$ , where $V$ is a $1^{--}$ vector-meson, are presented in detail. Emphasis is put on the use of the helicity formalism and the use of effective Lagrangians. We show the importance of ${{\rho}^{0}}-{\omega}$ mixing in enhancing the direct $CP$ violation (DCPV) when the pion-pion invariant mass is near the mass of the $\omega$ .
