SU(3) Mixing for Excited Mesons
W. S. Carvalho, A. S. de Castro, A. C. B. Antunes
The SU(3)-flavor symmetry breaking and the quark-antiquark annihilation mechanism are taken into account for describing the singlet-octet mixing for several nonets assigned by Part…
Some exact solutions of the Dirac equation
A. S. de Castro, J. Franklin
Exact analytic solutions are found to the Dirac equation for a combination of Lorentz scalar and vector Coulombic potentials with additional non-Coulombic parts. An appropriate lin…
Absence of Gluonic Components in Axial and Tensor Mesons
W. S. Carvalho, A. S. de Castro, A. C. B. Antunes
A quarkonium-gluonium mixing scheme previously developed to describe the characteristic of the pseudoscalar mesons is applied to axial and tensor mesons. The parameters of the mode…
Exact Solutions of the Dirac Equation for Modified Coulombic Potentials
Antonio Soares de Castro, Jerrold Franklin
Exact solutions are found to the Dirac equation for a combination of Lorentz scalar and vector Coulombic potentials with additional non-Coulombic parts. An appropriate linear combi…
