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,

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 at $T > 0$ [PDF]

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.

Quarkonium: a theory overview [PDF]

Nuclear Physics A, 2019
Quarkonium has long been proposed as one of the golden probes to identify the phase transition from confined hadronic matter to the deconfined quark-gluon plasma in heavy-ion collisions. Since then, we have achieved a better understanding, not only about the propagation of quarkonium in-medium, but also about its production.

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).

Quarkonium formation time in quark-gluon plasma [PDF]

, 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 ...

Quarkonium dissociation by anisotropy [PDF]

Journal of High Energy Physics, 2013
We compute the screening length for quarkonium mesons moving through an anisotropic, strongly coupled N=4 super Yang-Mills plasma by means of its gravity dual. We present the results for arbitrary velocities and orientations of the mesons, as well as for arbitrary values of the anisotropy.

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.

Measurements of quarkonia production [PDF]

EPJ 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).
