abstract

The form factors in the radiative decay of $J/\psi$ to a scalar glueball are studied within quenched lattice QCD on anisotropic lattices. The continuum extrapolation is carried out by using two different lattice spacings. With the results of these form factors, the partial width of $J/\psi$ radiatively decaying into the pure gauge scalar glueball is predicted to be 0.35(8) keV, which corresponds to a branching ratio of 3.8(9)x10^{-3}. By comparing with the experiments, out results indicate that f_0(1710) has a larger overlap with the pure gauge glueball than other related scalar mesons.

  1. Scalar glueball-$s\bar{s}$ mixing in one flavor lattice QCD

    hep-lat 2026-07 conditional novelty 7.0 of 10

    A lattice QCD simulation with one dynamical strange quark finds a large scalar glueball-s̄s mixing angle |θ|≈40.7(2.7)° and mixing energy x_s≈239(24) MeV, implying strong glueball-strange-quark mixing.

  2. Investigate the glueball-like particle $X(2370)$ in $B$ meson decays

    hep-ph 2025-01 conditional novelty 4.0 of 10

    Predictions for B to X(2370) branching fractions, around 10^-6 semileptonic and 10^-8 nonleptonic, suggest the glueball candidate is within Belle-II's reach.
