Study of the quasi-two-body decays $$B^{0}_{s} \rightarrow \psi (3770) (\psi (3686))\pi ^+\pi ^-$$ Bs0→ψ(3770)(ψ(3686))π+π- with perturbative QCD approach
Abstract In this note, we study the contributions from the S-wave resonances, $$f_{0}(980)$$ f0(980) and $$f_{0}(1500)$$ f0(1500) , to the $$B^{0}_{s}\rightarrow \psi (3770)\pi ^ {+}\pi ^{-}$$ Bs0→ψ(3770)π+π- decay by introducing the S-wave $$\pi \pi $$ ππ distribution amplitudes within the framewor...
