Abstract

We estimate final state interactions in the B-meson decays into two pions by the Regge model. We consider Pomeron exchange and the leading Regge trajectories that can relate intermediate particles to the final state. In some cases, most notably B→π0π0 and B→π+π-, the effect is relevant and produces a better agreement between theory and experiment.
