Book excerpt: We consider nonresonant contributions in the Dalitz plot analysis of B[yields][rho][pi][yields][pi][sup+][pi][sup -][pi][sup 0] decay and their potential impact on the extraction of the CKM parameter[alpha]. In particular, we examine the role of the heavy mesons B* and B[sub 0], via the process B[yields][pi](B*, B[sub 0])[yields][pi][sup+][pi][sup -][pi][sup 0], and their interference with resonant contributions in the[rho]-mass region. We discuss the inherent uncertainties and suggest that the effects may be substantially smaller than previously indicated.
