Abstract
We consider nonresonant contributions in the Dalitz-plot analysis of B→ρπ→π+π-π0 decay and their potential impact on the extraction of the Cabibbo-Kobayashi-Maskawa parameter α. In particular, we examine the role of the heavy mesons B* and B0, via the process B→π(B*,B 0)→π+π-π0, and their interference with resonant contributions in the ρ-mass region. We discuss the inherent uncertainties and suggest that the effects may be substantially smaller than previously indicated.
