Description:
Author(s): Wen-Fei Wang, Hsiang-nan Li, Wei Wang, and Cai-Dian Lü We study S -wave resonance contributions to the B ( s ) 0 → J / ψ π + π − and B s → π + π − μ + μ − decays in the perturbative QCD framework by introducing two-hadron distribution amplitudes for final states. The Breit–Wigner formula for the f 0 ( 500 ) , f 0 ( 1500 ) , and f 0 ( 1790 ) resonances and the Flatté model for the f 0 ( 980 ) r... [Phys. Rev. D 91, 094024] Published Thu May 21, 2015
