- W3100837851 abstract "The rare cascade $B_{s}$ ${to}$ ${phi}f_{0}(980)$ ${to}$ ${phi},{pi}^{+}{pi}^{-}$ decay is studied with the perturbative QCD approach based on the formula for the quasi two-body decay, where the two-pion pair originates from the $S$-wave resonant $f_{0}(980)$ state. It is found that with the introduction of the nonperturbative two-pion distribution amplitudes and the Flatt'{e} parameterization of the scalar form factor for the $f_{0}(980)$ resonance, the branching ratio in the mass range 400 MeV $<$ $m({pi}^{+}{pi}^{-})$ $<$ 1600 MeV is ${cal B}_{rm theo}(B_{s}^{0}, {to},{phi},f_{0}(980),{to},{phi},{pi}^{+},{pi}^{-})$ $=$ $[1.31_{-0.31}^{+0.40}(a_{{pi}{pi}}){}_{-0.16}^{+0.19}(m_{b}) {}_{-0.09}^{+0.10}(text{CKM})]{times}10^{-6}$, where the uncertainties come from the parameter $a_{{pi}{pi}}$ of the two-pion distribution amplitudes, the $b$ quark mass $m_{b}$, the Cabibbo-Kobayashi-Maskawa (CKM) factors, respectively. This result agrees with the recent LHCb measurement within uncertainties, ${cal B}_{rm exp}(B_{s}^{0},{to},{phi}, f_{0}(980),{to},{phi},{pi}^{+},{pi}^{-})$ $=$ $(1.12{pm}0.16^{+0.09}_{-0.08}{pm}0.11){times}10^{-6}$, where the errors are statistical, systematic and from the normalization, respectively." @default.
