Heavy vector mesons provide important information about the quark gluon plasma (QGP) formed in heavy ion collisions. This happens because the fraction of quarkonium states that are produced depends on the properties of the medium. The intensity of the dissociation process in a plasma is affected by the temperature, the chemical potential and the presence of magnetic fields. These effects have been studied by many authors in the recent years. Another important factor that can affect the dissociation of heavy mesons, and still lacks of a better understanding, is the rotation of the plasma. Non central collisions form a plasma with angular momentum. Here we use a holographic model to investigate the thermal spectrum of bottomonium quasi-states in a rotating medium in order to describe how a non vanishing angular velocity affects the dissociation process.

  1. Spectral Functions of $J/\psi$ Meson in Rotating Thermal Background from Holography

    hep-th 2026-08 conditional novelty 6.0 of 10

    In a rotating thermal medium modeled by soft-wall holography, J/ψ spectral peaks split by −ΩJ_z along the rotation axis and acquire projection-dependent distortions for transverse momentum.

  2. Non linear Regge trajectories of quarkonia from holography

    hep-ph 2025-12 conditional novelty 6.0 of 10

    A bottom-up AdS/QCD model with a new dilaton background produces the n^(2/3) Regge trajectories of quarkonia, matching experimental masses and decay constants.

  3. Holographic spectral functions of exotic spin-1 mesons

    hep-ph 2026-07 conditional novelty 5.0 of 10

    In a soft-wall holographic model with gluon condensate, the π1 hybrid and Zc tetraquark-like ground states both melt below the deconfinement temperature, with Zc melting slightly earlier and a larger condensate delayi...

  4. Holography and charmonium structure in a finite density plasma

    hep-ph 2025-05 conditional novelty 4.0 of 10

    The authors extend a holographic string model of charmonium to finite baryon density and derive a dissociation curve where the string tension jumps to zero, indicating a first-order quarkonium dissociation transition.
