- W2608278316 abstract "In this work, we calculate the $CP$-averaged branching ratios and direct $CP$-violating asymmetries of the quasi-two-body decays $B_{(s)}to P rho^prime(1450), Prho^{primeprime}(1700)to P pipi$ by employing the perturbative QCD (PQCD) factorization approach, where $P$ is a light pseudoscalar meson $K, pi, eta$ and $eta^{prime}$. The considered decay modes are studied in the quasi-two-body framework by parameterizing the two-pion distribution amplitude $Phi_{pipi}^{rm P}$. The $P$-wave time-like form factor $F_{pi}$ in the resonant regions associated with the $rho^prime(1450)$ and $rho^{primeprime}(1700)$ is estimated based on available experimental data. The PQCD predictions for the $CP$-averaged branching ratios of the decays $B_{(s)}to Prho^prime(1450), Prho^{primeprime}(1700)to Ppipi$ are in the order of $10^{-7} sim 10^{-9}$. The branching ratios of the two-body decays $B_{(s)}to Prho^prime(1450), Prho^{primeprime}(1700)$ are extracted from the corresponding quasi-two-body decay modes. The whole pattern of the pion form factor-squared $|F_pi|^2$ measured by {it BABAR} Collaboration could also be understood based on our studies. Our PQCD predictions will be tested by the precise data from the LHCb and the future Belle II experiments." @default.
