Abstract
An assumption of isospin symmetry permits the determination of sin (2α) from the experimental study of B→ππ decays. Isospin, however, is merely an approximate symmetry; its breaking predicates a theoretical systematical error σαIB in the extraction of α. We focus on the impact of π0-η,η′ mixing, as well as the manner in which it is amenable to empirical constraint, and determine that σαIB can potentially be controlled to O(1°).
