Description:
Author(s): Hai-Bing Fu, Long Zeng, Wei Cheng, Xing-Gang Wu, and Tao Zhong We make a detailed study on the J / ψ meson longitudinal leading-twist distribution amplitude ϕ 2 ; J / ψ ∥ by using the QCD sum rules within the background field theory. By keeping all the nonperturbative condensates up to dimension 6, we obtain accurate QCD sum rules for the moments ⟨ ξ n ; J / ψ ∥ ⟩ . The first t... [Phys. Rev.
