Mass Spectra, Radii, and Decay Widths of Toponium
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.In this work, the radial Schrodinger equation with a nonrelativistic quark potential model (NRQPM) is solved numerically by employing the shooting method. Calculated numerical wave functions (or solutions) are used to compute the masses, root mean square (RMS) radii, E1, M1 radiative transition widths, annihilation decay widths, and branching ratios of

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 ...

Two-loop integrals for CP-even heavy quarkonium production and decays: elliptic sectors
Journal of High Energy Physics, 2018 By employing the differential equations, we compute analytically the elliptic sectors of two-loop master integrals appearing in the NNLO QCD corrections to CP-even\ heavy quarkonium exclusive production and decays, which turns out to be the last and ...

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.

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.

Quarkonium at Finite Temperature [PDF]
Nuclear Physics A, 2007 Lattice QCD studies on charmonium at finite temperature are presented After a discussion about problems for the Maximum Entropy Method applied to finite temperature lattice QCD, I show several results on charmonium spectral functions. The ``wave function'' of charmonium is also discussed to study the spatial correlation between quark and anti-quark in ...

QUARKONIUM AT FINITE TEMPERATURE [PDF]
, 2010 We discuss properties of heavy quarkonium states at high temperatures based on lattice QCD and potential models. We review recent progress made in lattice calculations of spatial static quark anti-quark correlators as well as quarkonium correlators in Euclidean time.
