QCD Factorization in $B$ Decays into $\rho \pi$

Abstract

Based on the QCD factorization approach we analyse the branching ratios for the channel $B\to \rho \pi$. From the comparisons with experimental data provided by CLEO, BELLE and BABAR we constrain the form factor $F^{B\to \pi }(m_{\rho }^2)$ and propose boundaries for this form factor depending on the CKM matrix element parameters $\rho$ and $\eta$.
