abstract

Analyzing correlation functions of charmonia at finite temperature ($T$) on $32^3\times(32-96)$ anisotropic lattices by the maximum entropy method (MEM), we find that $J/\psi$ and $\eta_c$ survive as distinct resonances in the plasma even up to $T \simeq 1.6 T_c$ and that they eventually dissociate between $1.6 T_c$ and $1.9 T_c$ ($T_c$ is the critical temperature of deconfinement). This suggests that the deconfined plasma is non-perturbative enough to hold heavy-quark bound states. The importance of having sufficient number of temporal data points in MEM analyses is also emphasized.

  1. Thermal Static Potential and Pseudo-Scalar Quarkonium Spectral Functions from 2+1 Flavor Lattice QCD

    hep-lat 2025-05 conditional novelty 6.0 of 10

    Pseudoscalar quarkonium spectral functions built from a non-perturbative complex thermal potential show eta_c close to melting at 1.6 Tpc while eta_b remains a narrow, well-defined state.

  2. In-medium bottomonium properties from lattice NRQCD calculations with extended meson operators

    hep-lat 2025-01 conditional novelty 6.0 of 10

    Bottomonium masses do not shift in the quark-gluon plasma up to 250 MeV, but thermal widths are nonzero and highly sensitive to the assumed spectral function shape.

  3. Thermal Broadening of Bottomonia: Lattice Non-Relativistic QCD with Extended Operators

    hep-lat 2019-08 conditional novelty 6.0 of 10

    Using extended operators, lattice NRQCD correlators at T=151-334 MeV are fit with broadened spectral functions, yielding thermal widths for bottomonia that grow with temperature, especially for P-waves.

  4. Quantum Brownian motion of a heavy quark pair in the quark-gluon plasma

    nucl-th 2019-08 conditional novelty 6.0 of 10

    Heavy quarkonium's relative motion in the quark-gluon plasma can be evolved with a Lindblad master equation whose stochastic unraveling includes drag, and in one-dimensional simulations the pair thermalizes with a tem...

  5. Spin structure of spin-1 charmonium states near $T_c$

    hep-ph 2025-04 reject novelty 5.0 of 10

    The paper derives spin-decomposed Wilson coefficients for the twist-2 gluon condensate and uses them to argue that charmonium spin fractions shift by a few percent near T_c, with the total spin unchanged by definition.

  6. Charmonium properties at high temperatures from lattice QCD

    hep-lat 2026-05 unverdicted novelty 4.0 of 10

    Lattice QCD calculations indicate charmonium states persist below the open-charm threshold up to 305 MeV but develop temperature-dependent thermal widths that increase with state size.
