Quasi-Two-Body $B\to P(K^{+}{K}^{-},{\pi }^{+}{\pi }^{-})$ Decays with $f_0(980)$ Resonance

Ya-Xin Wang, Jun-Peng Wang, Ying Li +1

In this study, we investigate the $CP$-averaged branching fractions and direct $CP$ asymmetries in the quasi-two-body decays $B\to P(f_0(980)\to )(K^{+}{K}^{-},{\pi }^{+}{\pi }^{-})$ within the fra…
