Description:
Author(s): Xin Liu, Hsiang-nan Li, and Zhen-Jun Xiao We point out that the recent Belle measurements of the B d / s → J / ψ η (′) decays imply large pseudoscalar glueball contents in the η (′) meson. These decays are studied in the perturbative QCD approach, considering the η - η ′ - G mixing, where G represents the pseudoscalar glueball. We show that the perturbati... [Phys. Rev.
