Hadronic pollution in B $\to \rho\pi$?

The B -> 3pi decay via rho has been shown, in two independent calculations, to be very sensible to the B -> sigma pi background. This potentially complicates the extraction of alpha through the isospin analysis of B -> rho pi. I will briefly review this topic.
