Final-state Rescattering Effects on B_d-->ππDecays and CP Violation

Abstract

The significance of final-state interactions in B_d-->ππdecays is phenomenologically demonstrated by taking elastic ππ--ππand inelastic ππ--D\bar{D} rescattering effects into consideration. We find that the present experimental data on B^0_d-->π^+π^- can well be understood in this approach without fine-tuning of the input parameters, and large CP-violating asymmetries are expected to manifest themselves in such charmless rare processes.
