Charmonium Properties Using the Discrete Variable Representation (DVR) Method

open access: yesAdvances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
The Schrödinger equation is solved numerically for charmonium using the discrete variable representation (DVR) method. The Hamiltonian matrix is constructed and diagonalized to obtain the eigenvalues and eigenfunctions. Using these eigenvalues and eigenfunctions, spectra and various decay widths are calculated.

HEAVY QUARKONIUM [PDF]

open access: yesLepton and Photon Interactions at High Energies, 2004
I review heavy quarkonium physics in view of recent experimental results. In particular, I discuss new results on spin singlet states, photon and hadronic transitions, D–states and discovery of the yet unexplained narrow X(3872) state.

Charmonium and exotics from lattice QCD [PDF]

open access: yesEPJ 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

Two-loop Correction to the Leptonic Decay of Quarkonium [PDF]

open access: yes, 1997
Applying asymptotic expansions at threshold, we compute the two-loop QCD correction to the short-distance coefficient that governs the leptonic decay $\psi\to l^+ l^-$ of a S-wave quarkonium state and discuss its impact on the relation between the ...

Scalar quarkonium masses [PDF]

open access: yesNuclear 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 $f_J(1710)$.

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,

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.
