摘要

We show that the large, direct CP-violation parameter A(pipi) = -C-pipi, reported by the BELLE collaboration in the decays B-0 (B-0) --> pi(+)pi(-), implies an unusual situation in which the presence of a very large difference between two strong-interaction phases (similar to -110degrees) plays an essential role. We make the demonstration within a model of strong, two-body quasi-elastic interactions between physical hadrons. The model can accommodate a large difference between two strong-interaction phases, for which it provides a natural enhancement.
