In this paper we have calculated transition magnetic moments and radiative decay widths of light and heavy mesons using a relativistic potential model of independent quarks with its parameters determined from a fit to the mass of ground state mesons in the strange, charm and bottom flavor sectors. The results are in agreement with the experimental data.

Experimental Values

The ground state spectra of the nucleon octet are studied in a relativistic logarithmic potential model taking into account the contributions of the quark–gluon coupling due to one-gluon-exchange interactions and that of Goldstone boson (π, η, K) exchange interactions between the constituent quarks in a baryon. The baryons are assumed here as an assembly of independent quarks confined in a first approximation by an effective logarithmic potential which presumably represents the nonperturbative gluon interactions, including the gluon self-couplings. This model treats the meson degree of freedom in a perturbative manner as is done in the cloudy bag model. The mass spectrum of low-lying baryons so obtained with the quark–gluon coupling constant αc = 0.195 agree reasonably well with the corresponding experimental values.

The decay widths for M1 transitions of mesons are calculated in a relativistic potential model of independent quarks with its parameters determined from a fit to the mass splittings of the ground state mesons in the strange, charm and bottom flavor sector. A more realistic calculation of the decay widths is performed beyond static approximation incorporating some momentum dependence due to recoil of the daughter meson. The model accounts well for the observed decay widths of light mesons and predicts decay rates of heavy mesons which are comparable with those of other model calculations.

Radial Wave Equation

In this paper, a non-relativistic potential model is used to find the solution of radial Schrodinger wave equation by using Crank Nicolson discretization for heavy quarkonia ( ̅, ̅). After solving the Schrodinger radial wave equation, the mass spectrum and hyperfine splitting of heavy quarkonia are calculated with and without relativistic corrections. The root means square radii and decay constants for S and P states of c ̅ and ̅ mesons by using the realistic and simple harmonic oscillator wave functions. The calculated results of mass, hyperfine splitting, root means square radii and decay constants agreed with experimental and theoretically calculated results in the literature.

We calculate the eigenvalues and their corresponding eigenfunctions of the Bohr’s collective Hamiltonian with the help of the modified Pöschl–Teller (MPT) potential model within [Formula: see text]-unstable structure. Our numerical results for the ground state (g.s.) [Formula: see text] and [Formula: see text] band heads, together with the electric quadrupole [Formula: see text] transition rates, are displayed and compared with the available experimental data.
