Real time quarkonium transport coefficients in open quantum systems from Euclidean QCD [PDF]
Physical Review D, 2023 Recent open quantum system studies showed that quarkonium time evolution inside the quark-gluon plasma is determined by transport coefficients that are defined in terms of a gauge invariant correlator of two chromoelectric field operators connected by an

Hyperfine splittings of heavy quarkonium hybrids [PDF]
Physical Review D, 2023 In the framework of the Born-Oppenheimer Effective Field Theory, the hyperfine structure of heavy quarkonium hybrids at leading order in the 1/m Q expansion is determined by two potentials.

Sequential Quarkonium Suppression
, 2001 We use recent lattice data on the heavy quark potential in order to determine the dissociation temperatures of different quarkonium states in hot strongly interacting matter.

The complex heavy quarkonium potential with the Gribov–Zwanziger action [PDF]
The European Physical Journal C, 2023 Gribov–Zwanziger prescription in Yang–Mills theory improves the infrared dynamics. In this work, we study the static potential of a heavy quark-antiquark pair with the HTL resummed perturbation method within the Gribov–Zwanziger approach at finite ...

Quarkonium spin alignment in a vortical medium [PDF]
Physical Review D, 2023 We use a potential model to investigate the phenomenology of quarkonium in a thermal rotating medium, where vorticity and spin density are not necessarily in equilibrium.

Impact of heavy quark and quarkonium data on nuclear gluon PDFs [PDF]
Physical Review D, 2022 A clear understanding of nuclear parton distribution functions (nPDFs) plays a crucial role in the interpretation of collider data taken at the Relativistic Heavy Ion Collider (RHIC), the Large Hadron Collider (LHC) and in the near future at the Electron-

Heavy quarkonium dynamics at next-to-leading order in the binding energy over temperature [PDF]
Journal of High Energy Physics, 2022 Using the potential non-relativistic quantum chromodynamics (pNRQCD) effective field theory, we derive a Lindblad equation for the evolution of the heavy-quarkonium reduced density matrix that is accurate to next-to-leading order (NLO) in the ratio of ...

Rapidity evolution of the entanglement entropy in quarkonium: Parton and string duality [PDF]
Physical Review D, 2022 We investigate the quantum entanglement in rapidity space of the soft gluon wave function of a quarkonium, in theories with non-trivial rapidity evolutions. We found that the rapidity evolution drastically changes the behavior of the entanglement entropy,

Entropic force and real-time dynamics of holographic quarkonium in a magnetic field [PDF]
Physical Review D, 2022 We continue the study of a recently constructed holographic QCD model supplemented with magnetic field. We consider the holographic dual of a quark, anti-quark pair and investigate its entropy beyond the deconfinement phase transition in terms of ...

Two-loop master integrals for pseudo-scalar quarkonium and leptonium production and decay [PDF]
Journal of High Energy Physics, 2022 We compute the master integrals relevant for the two-loop corrections to pseudo-scalar quarkonium and leptonium production and decay. We present both analytic and high-precision numerical results.
