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

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,

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).

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).

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.

Quarkonia as probes of initial and final states in small systems with ALICE [PDF]

EPJ Web of Conferences
The 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.

Excitation Function of Initial Temperature of Heavy Flavor Quarkonium Emission Source in High Energy Collisions

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
The transverse momentum spectra of J/ψ, ψ(2S), and Y(nS, n = 1, 2, 3) produced in proton‐proton (p + p), proton‐antiproton p+p¯, proton‐lead (p + Pb), gold‐gold (Au + Au), and lead‐lead (Pb + Pb) collisions over a wide energy range are analyzed by the (two‐component) Erlang distribution, the Hagedorn function (the inverse power‐law), and the Tsallis ...

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

Physics 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.

Quarkonium Phenomenology from a Generalised Gauss Law

Universe, 2019
We present an improved analytic parametrisation of the complex in-medium heavy quark potential derived rigorously from the generalised Gauss law. To this end we combine in a self-consistent manner a non-perturbative vacuum potential with a weak-coupling ...
