Quarkonium production in Pb-Pb collisions at √SNN = 5.02 TeV with ALICE

open access: yesEPJ Web of Conferences, 2018
Ultra-relativistic heavy-ion collisions at the Large Hadron Collider provide a unique opportunity to study the properties of matter at extreme energy densities where a phase transition from the hadronic matter to a deconfined medium of quarks and gluons,

Schrödinger spectrum generated by the Cornell potential

open access: yesOpen Physics, 2015
The eigenvalues Ednl (a, c) of the d-dimensional Schrödinger equation with the Cornell potential V(r) = −a/r + c r, a, c > 0 are analyzed by means of the envelope method and the asymptotic iteration method (AIM).

Measurements of quarkonia production [PDF]

open access: yesEPJ Web of Conferences
Quarkonium production in high-energy hadronic collisions is a useful tool to investigate fundamental aspects of Quantum Chromodynamics, from the proton and nucleus structure to deconfinement and the properties of the Quark Gluon Plasma (QGP).

Entropic destruction of heavy quarkonium in quark-gluon plasma with gluon condensate

open access: yesPhysics Letters B, 2020
It has been argued that the peak of the quarkonium entropy at the deconfinement transition is related to the entropic force which induces dissociation of quarkonium states.

Gluon fragmentation into heavy quarkonium [PDF]

open access: greenPhysical Review Letters, 1993
The dominant production mechanism for heavy quark-antiquark bound states in very high energy processes is fragmentation, the splitting of a high energy parton into a quarkonium state and other partons. We show that the fragmentation functions $D(z, )$ describing these processes can be calculated using perturbative QCD.

Quarkonium formation time in quark-gluon plasma [PDF]

open access: yes, 2013
The quarkonium formation time in a quark-gluon plasma (QGP) is determined from the space-time correlator of heavy quark vector currents using the quarkonium in-medium mass and wave function obtained from heavy quark potentials extracted from the lattice ...

Phenomenological study of quarkonium suppression and the impact of the energy gap between singlets and octets [PDF]

open access: yesPhysical Review D, 2021
The study of heavy quarkonium suppression in heavy-ion collisions represents an important source of information about the properties of the quark-gluon plasma produced in such collisions. In a previous paper, we have considered how to model the evolution

Spin Splitting Spectroscopy of Heavy Quark and Antiquarks Systems

open access: yesAdvances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
Phenomenological potentials describe the quarkonium systems like cc¯,bb,¯ and b¯c where they give a good accuracy for the mass spectra. In the present work, we extend one of our previous works in the central case by adding spin‐dependent terms to allow for relativistic corrections.
