We show that the large, direct CP-violation parameter$A_{\pi\pi}=-C_{\pi\pi}$, reported by the BELLE collaboration in the decaysBbar^0(B^0) -> \pi^+\pi^-, implies an unusual situation in which the presenceof a very large difference between two strong-interaction phases ~ -110 deg.plays an essential role. We make the demonstration within a model of strong,two-body quasi-elastic interactions between physical hadrons. The model canaccommodate a large difference between two strong-interaction phases, for whichit provides a natural enhancement.Comment: 6 pages, no figure

A new implication for strong interactions if large, direct CP violation in bar B0(B0)→π+π−is confirmed
