Final state interactions in the decay $B^0\to {\eta }_c{K}^{\ast }$

Abstract

In this article, we study the final-state rescattering effects in the decay $B^0\to {\eta }_c{K}^{\ast }$, the numerical results indicate the corrections are comparable with the contribution from the naive factorizable amplitude, and the total amplitudes can accommodate the experimental data.
