QQ-onia package: a numerical solution to the Schrödinger radial equation for heavy quarkonium
Description
Abstract This paper presents the basics of the QQ-onia package, a software based upon the Numerov O (h^6 ) method which can be used to solve the Schrödinger radial equation using a suitable potential V (r) for the heavy quarkonium system. This package also allows the analysis of relevant properties of those resonances such as the square of the wave functions at the origin, their corresponding derivatives for l ≠ 0 states, typical heavy-quark velocities, and mean square radii. Besides, it includes a to... Title of program: QQ-onia package Catalogue Id: AECQ_v1_0 Nature of problem Software to solve the Schrödinger radial equation using a suitable potential V (r) for the heavy quarkonium system, allowing to perform spectroscopy. It also allows the analysis of relevant quantities of those resonances such as the square of the wave functions at the origin, their corresponding derivatives for l ≠ 0 states, typical heavy-quark velocities, and mean square radii. The package is a (userfriendly) multipurpose tool for dealing with different heavy quarkonium systems, providing a way ...
