Looking for Delta I = 5/2 amplitude components in B -> pi pi and B -> rho rho experiments

Abstract

We discuss how experiments measuring B -> pi pi and B -> rho rho may be used to search for a Delta I = 5/2 amplitude component. This component could be the explanation for a recent (albeit very tentative) hint from B(Bbar) -> rho rho decays that the isospin triangles do not close.
