abstract

We present a realistic lattice QCD study on low-energy $N$-$J/\psi$ and $N$-$\eta_c$ interactions based on (2+1) flavor configurations with nearly physical pion mass $m_\pi=146$ MeV. The interactions, extracted from the spacetime correlations of nucleon and charmonium system by using the HAL QCD method, are found to be attractive in all distances and possess a characteristic long-range tail consistent with the two-pion exchange potential. The resulting $S$-wave scattering lengths are $0.30(2)\left(^{+0}_{-2}\right)$ fm, $0.38(4)\left(^{+0}_{-3}\right)$ fm, and $0.21(2)\left(^{+0}_{-1}\right)$ fm for spin-$3/2$ $N$-$J/\psi$, spin-$1/2$ $N$-$J/\psi$, and spin-$1/2$ $N$-$\eta_c$, respectively. Our results are orders of magnitude larger than those from the photoproduction experiments assuming the vector meson dominance. Our findings may provide deeper understanding of the nonperturbative QCD phenomena ranging from the origin of nucleon mass to the in-medium $J/\psi$ mass modification as well as the properties of hidden-charm pentaquark states.

  1. $S$-wave kaon-nucleon interactions from lattice QCD at the physical point

    hep-lat 2025-08 conditional novelty 6.0 of 10

    First physical-point lattice QCD calculation of S-wave kaon-nucleon interactions finds no resonance or bound state, with scattering lengths -0.226(5) fm (I=1) and +0.031(62) fm (I=0).

  2. Heavy-heavy and heavy-light mesons in cold nuclear matter

    nucl-th 2025-06 conditional novelty 3.0 of 10

    Using the quark-meson coupling model and effective Lagrangians, heavy and heavy-light mesons are predicted to feel attractive potentials in nuclei and form bound states, including new B_c-nucleus states.

  3. Unquenched Charmonium and Beyond

    hep-ph 2026-02 conditional novelty 2.0 of 10

    This Lanzhou-group review argues that coupled-channel (unquenched) effects, not exotic constituents, are the common thread explaining charmonium anomalies from the rho-pi puzzle to the Y-problem states.

  4. Recent progress on charmed hadron interactions from lattice QCD

    hep-lat 2025-09 conditional novelty 2.0 of 10

    A review of lattice QCD results on charmed hadron interactions: T_cc near threshold, an attractive N-J/psi force, and an Omega_ccc-Omega_ccc state near unitarity.
