The Effect of Debye Mass on the Mass Spectra of Heavy Quarkonium System and Its Thermal Properties with Class of Yukawa Potential

Jordan journal of physics, 2023
: In this research, we first solve the radial Schrödinger equation analytically using the Nikiforov–Uvarov method with the class of Yukawa potential by replacing the screening parameter with Debye mass and the energy eigenvalues and Then, the ...

Quarkonium propagation in the quark–gluon plasma

The European Physical Journal Special Topics, 2021
In relativistic heavy ion collisions at RHIC and the LHC, a quark–gluon plasma (QGP) is created for a short duration of about 10 fm/c. Quarkonia (bound states of cc¯\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage ...

Analytical Solutions of the Schrödinger Equation with Kratzer-screened Coulomb Potential for a Quarkonium System

Bulletin of Pure & Applied Sciences- Physics, 2021
In this work, we obtain the Schr\"odinger equation solutions for the Kratzer potential plus screened Coulomb potential model using the series expansion method.

Quarkonium annihilation rates

Physical Review D, 1988
Recent measurements of ratios of quarkonium annihilation rates are used to evaluate the strong fine-structure constant ${\ensuremath{\alpha}}_{s}$. Expressions are presented for QCD radiative corrections with ${\ensuremath{\alpha}}_{s}$ referred to the quark-mass scale.

Nuclear-bound quarkonium

Physical Review Letters, 1990
We show that the QCD van der Waals interaction due to multiple gluon exchange provides a new kind of attractive nuclear force capable of binding heavy quarkonia to nuclei. The parameters of the potential are estimated by identifying multigluon exchange with the Pomeron contributions to elastic meson-nucleon scattering.

Relativistic quarkonium dynamics

Physical Review D, 1986
We present, in the framework of relativistic quantum mechanics of two interacting particles, a general model for quarkonium systems satisfying the following four requirements: confinement, spontaneous breakdown of chiral symmetry, soft explicit chiral-symmetry breaking, short-distance interactions of the vector type.
