QCD Factorization in $B$ Decays into $ρπ$

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