Title: The charmonium and bottomonium mass spectroscopy with a simple approximation of the kinetic term
Author: Bernardini, AE
Dobrigkeit, C
Abstract: In this paper we propose a particular description of meson spectroscopy, with emphasis on heavy bound states such as charmonia and bottomonia, after working on the main aspects of the construction of an effective potential model. We use the prerogatives from 'soft QCD' to determine the effective potential terms, establishing the asymptotic Coulomb term from one gluon exchange approximation. At the same time, a linear confinement term is introduced in agreement with the QCD and phenomenological prescription. The main aspect of this work is the simplification in the calculation, a consequence of a precise and simplified description of the kinetic term of the Hamiltonian. With this proposition we perform the calculations of mass spectroscopy for charmonium and bottomonium mesons and discuss the real physical possibilities of developing a generalized potential model, its possible advantages relative to experimental parametrization and complexity in numerical calculations.
