Lattice calculations allow us to probe the low-lying, non-perturbative spectrum of QCD using first principles numerical methods. Here we present the low-lying spectrum in the scalar sector with vacuum quantum numbers including, in fully dynamical QCD for the first time, the mixing between glueball, q-qbar, and meson-meson operators.

Discussion (0). Continue with ORCID to comment.

  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. Flavor mixing in charmonium and light mesons with optimal distillation profiles

    hep-lat 2025-02 conditional novelty 6.0 of 10

    In two lattice QCD ensembles, flavor-singlet charmonium and light-meson operators mix with each other and with gluonic operators, and adding a two-pion operator reveals an additional low-lying state.

  3. Update on Glueballs

    hep-lat 2025-02 unverdicted novelty 2.0 of 10

    A lattice QCD review concludes that, based on exploratory calculations, no scalar hadron below roughly 2 GeV appears to be predominantly a glueball.
