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

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

Progress of Theoretical Physics Supplement, 2012 We report recent progress on theoretical investigations of quarkonia at finite temperature. We discuss medium modification of charmonia and bottomonia from a viewpoint of local operators and point out that while charmonia are sensitive to the deconfinement transition bottomonia will be modified at much higher temperatures.

Schrödinger spectrum generated by the Cornell potential
Open 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).

Fragmentation functions for a quark into a spin-singlet quarkonium: Different flavor case [PDF]
Physical Review D, 2021 In the paper, we calculate the fragmentation functions for a quark to fragment into a spin-singlet quarkonium, where the flavor of the initial quark is different from that of the constituent quark in the quarkonium.

Spin Splitting Spectroscopy of Heavy Quark and Antiquarks Systems
Advances 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.

Scalar quarkonium masses [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 We evaluate the valence approximation to the mass of scalar quarkonium for a range of different parameters. Our results strongly suggest that the infinite volume continuum limit of the mass of $s\overline{s}$ scalar quarkonium lies well below the mass of $f_J(1710)$.

Quarkonia as probes of initial and final states in small systems with ALICE [PDF]
EPJ Web of ConferencesThe multiple parton−parton interactions (MPIs) are an important element to describe the observed collective flow and strangeness enhancement in high multiplicity pp and p−Pb collisions, the so-called small systems.
