abstract

To investigate a recent proposal that J/$\psi$ production in ultra-relativistic nuclear collisions is of thermal origin we have reanalyzed the data from the NA38/50 collaboration within a thermal model including charm. Comparison of the calculated with measured yields demonstrates the non-thermal origin of hidden charm production at SPS energy. However, the ratio $\psi^{'}$/(J/$\psi)$ exhibits, in central nucleus-nucleus collisions, thermal features which lead us to a new interpretation of open charm and charmonium production at SPS energy. Implications for RHIC and LHC energy measurements will be discussed.

    hep-ph 2025-05 conditional novelty 8.0 of 10

    The chromoelectric adjoint correlators are evaluated at next-to-leading order, revealing a Wilson-line zero-mode induced asymmetry that matches lattice data at extremely high temperatures.

  2. Coupled charm and charmonium transport in a strongly coupled quark-gluon plasma

    nucl-th 2026-03 conditional novelty 7.0 of 10

    A unified T-matrix transport framework for charm-quark diffusion and charmonium kinetics with off-shell spectral functions recovers the statistical equilibrium limit and gives fair LHC charmonium R_AA data.

  3. Evidence for sequential $\Upsilon$(nS) suppression in light ion collisions

    nucl-ex 2026-07 conditional novelty 6.0 of 10

    First evidence of sequential Upsilon(nS) suppression in oxygen-oxygen and neon-neon collisions, with the Upsilon(3S)/Upsilon(2S) ratio reduced by 3.2 standard deviations.

  4. Nuclear modification of $B_c$ mesons in relativistic heavy-ion collisions based on a linear Boltzmann transport model

    hep-ph 2025-02 conditional novelty 5.0 of 10

    A linear Boltzmann transport model with Yukawa and string interactions reproduces the measured B_c nuclear modification in Pb+Pb collisions and predicts larger low-pT B_c R_AA in Au+Au at RHIC than at the LHC.

  5. Charmonium production at SPS and FAIR energies

    hep-ph 2026-05 unverdicted novelty 4.0 of 10

    Remler formalism with in-medium heavy-quark potential describes charmonium yields at SPS energies and supplies estimates for FAIR energies after calibration on p+p and p+A collisions.
