Description
On behalf of my colleagues, I will present a short review on our recent work [1] on
parametrizations of weak $B$ and $D$ decays into final
states composed of three light mesons, namely the various charge
states $\pi\pi\pi$, $K\pi\pi$ and $KK\bar K$.
These parametrizations are derived from previous calculations based on a quasi-two-body
factorization approach in which two-body hadronic final state
interactions are fully taken into account in terms of unitary $S$- and
$P$-wave $\pi\pi$, $\pi K$ and $K \bar K$ form factors.
They are an alternative to the isobar-model Dalitz-plot parametrizations and can be useful in the interpretation of CP asymmetries.
