Charmonium Properties Using the Discrete Variable Representation (DVR) Method
Advances 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.

Approximate solutions of the Schrödinger equation with Hulthén-Hellmann Potentials for a Quarkonium system [PDF]
Revista mexicana de física, 2021 Hulthén plus Hellmann potentials are adopted as the quark-antiquark interaction potential for studying the mass spectra of heavy mesons. We solved the radial Schrödinger equation analytically using the Nikiforov-Uvarov method.

Rigorous QCD analysis of inclusive annihilation and production of heavy quarkonium. [PDF]
Physical Review D, Particles and fields, 1994 A rigorous QCD analysis of the inclusive annihilation decay rates of heavy quarkonium states is presented. The effective-field-theory framework of nonrelativistic QCD is used to separate the short-distance scale of annihilation, which is set by the heavy

Non-Abelian electric field correlator at NLO for dark matter relic abundance and quarkonium transport [PDF]
Journal of High Energy Physics, 2021 We perform a complete next-to-leading order calculation of the non-Abelian electric field correlator in a SU( N c ) plasma, which encodes properties of the plasma relevant for heavy particle bound state formation and dissociation, and is different from ...

A dynamical Einstein-Born-Infeld-dilaton model and holographic quarkonium melting in a magnetic field [PDF]
Journal of High Energy PhysicsWe generalize the potential reconstruction method to set up a dynamical Einstein-Born-Infeld-dilaton model, which we then use to study holographic quarkonium melting in an external magnetic field.

Lepton 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]
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

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

Shedding Light on Hadronization by Quarkonium Energy Correlator. [PDF]
Physical Review LettersWe propose to measure the energy correlator in quarkonium production, which tracks the energy deposited in the calorimeter at the χ-angular distance away from the identified quarkonium.
