Final state interactions in the decay $B^0 \to η

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/208171In this article, we study the final-state rescattering effects in the decay $B^0 \to η_cK^*$, 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.11 pages, 1 figure, revised version, to appear in EPJCHigh Energy Physics - PhenomenologyFinal state interactions in the decay $B^0 \to η_c K^*$text
