A Guide to Light‐Cone PDFs from Lattice QCD: An Overview of Approaches, Techniques, and Results
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 Within the theory of Quantum Chromodynamics (QCD), the rich structure of hadrons can be quantitatively characterized, among others, using a basis of universal nonperturbative functions: parton distribution functions (PDFs), generalized parton distributions (GPDs), transverse momentum dependent parton distributions (TMDs), and distribution amplitudes ...

Cornell Potential: A Neural Network Approach
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 We solved Schrödinger equation with Cornell potential (Coulomb‐plus‐linear potential) by using neural network approach. Four different cases of Cornell potential for different potential parameters were used without a physical relevance. Besides that charmonium, bottomonium and bottom‐charmed spin‐averaged spectra were also calculated.

, 2017 In this addendum to Phys.\ Rev.\ D {\bf 95}, 054018 (2017) we recompute the rates for the decays of the Higgs boson to a vector quarkonium plus a photon, where the vector quarkonium is $J/\psi$, $\Upsilon(1S)$, $\Upsilon(2S)$, or $\Upsilon(3S)$.

Dissociation of J/ψ and Y Using Dissociation Energy Criteria in N‐Dimensional Space
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.The analytical exact iteration method (AEIM) has been widely used to calculate N‐dimensional radial Schrodinger equation with medium‐modified form of Cornell potential and is generalized to the finite value of magnetic field (eB) with quasiparticle approach in hot quantum chromodynamics (QCD) medium.

Unquenching the Quark Model in a Nonperturbative Scheme
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 In recent years, the discovery in quarkonium spectrum of several states not predicted by the naive quark model has awakened a lot of interest. A possible description of such states requires the enlargement of the quark model by introducing quark‐antiquark pair creation or continuum coupling effects.

Gluon fragmentation to ^3D_J quarkonia [PDF]
, 1997 We present a calculation of the leading order QCD fragmentation functions for gluons to split into spin-triplet D-wave quarkonia. We apply them to evaluate the gluon fragmentation contributions to inclusive ^3D_J quarkonium production at large transverse

Configuration entropy for quarkonium in a finite density plasma [PDF]
Physical Review D, 2020 In the recent years many examples appeared in the literature where the configuration entropy (CE), introduced by Gleiser and Stamatopoulos, plays the role of an indicator of stability of physical systems.

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.
