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…
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…
Mass effects in a Three-Body System Bound by Harmonic Oscilators
A. C. B. Antunes, L. J. Antunes
The problem of three different masses bound by harmonic oscillator potentials is solved exactly. It is shown that Jacobi coordinates cannot, in general, decouple this system into t…
A Three Configurations Diquark Model for Baryons
W. S. Carvalho, A. C. B. Antunes
The wave functions in the diquark-quark model for baryons are modified to take into account the effect of the different masses of the quarks in diquark formation. A spatial wave fu…
