Measuring $B \to \rho\pi$ decays and the unitarity angle $\alpha$

The decay mode B -> rho pi is currently studied as a channel allowing, inprinciple, to measure without ambiguities the angle alpha of the unitaritytriangle. It is also investigated by the CLEO Collaboration where a branchingratio larger than expected for the decay mode B+/- -> rho0 pi+/- has b...

description The decay mode B -> rho pi is currently studied as a channel allowing, inprinciple, to measure without ambiguities the angle alpha of the unitaritytriangle. It is also investigated by the CLEO Collaboration where a branchingratio larger than expected for the decay mode B+/- -> rho0 pi+/- has beenfound. We investigate the role that the B* and B(0+) resonances play in theseanalyses.
