Heavy Quarkonium States With Baryonic Chemical Potential [PDF]
Advances in High Energy PhysicsIn this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential.

The dipole picture and the non-relativistic expansion [PDF]
EPJ Web of Conferences, 2022 We study exclusive quarkonium production in the dipole picture at next-to-leading order (NLO) accuracy, using the non-relativistic expansion for the quarkonium wavefunction.

Effect of a Wake-Field on the Dissociation of Quarkonium in Collisional Quark–Gluon Plasma
Particles, 2023 We have studied wake effects on the dissociation of heavy quarkonia states J/ψ and Y by introducing an in-medium modification to the inter-quark potential.

Quarkonia as probes of the QGP and of the initial stages of the heavy-ion collision with ALICE [PDF]
EPJ Web of Conferences, 2022 Studies of quarkonium production in heavy-ion collisions can be used for probing QGP properties. The suppression and regeneration of bound quarkonium states is sensitive to the medium properties.

Nonequilibrium evolution of quarkonium in medium [PDF]
EPJ Web of Conferences, 2022 We review recent progress in open quantum system approach to the description of quarkonium in the quark-gluon plasma. A particular emphasis is put on the Lindblad equations for quarkonium and its numerical simulations.

Quarkonium production and polarization: where do we stand? [PDF]
EPJ Web of Conferences, 2022 We review the current status of heavy quarkonium production phenomenology based on nonrelativistic effective field theories, focusing on spintriplet S -wave states such as J/ψ, ψ(2S ), and ϒ.

Probing the Hot QCD Matter via Quarkonia at the Next-Generation Heavy-Ion Experiment at LHC
Particles, 2023 Quarkonia represent one of the most valuable probes of the deconfined quark–gluon hot medium since the very first experimental studies with ultrarelativistic heavy-ion collisions. A significant step forward in characterizing the QCD matter via systematic

Quarkonium semiclassical transport in quark-gluon plasma: factorization and quantum correction
Journal of High Energy Physics, 2021 We study quarkonium transport in the quark-gluon plasma by using the potential nonrelativistic QCD (pNRQCD) effective field theory and the framework of open quantum systems. We argue that the coupling between quarkonium and the thermal bath is weak using

Charmonium and exotics from lattice QCD [PDF]
EPJ Web of Conferences, 2019 We review selected lattice results on the charmonium spectrum and first attempts to search for the existence of exotic states. The hadro-quarkonium model was proposed to interpret some of the exotic states as a quarkonium core inside a hadron. We present
