Relativistic corrections to the neutron electric dipole moment in valence quark models

Technical Report:

Abstract

It is shown that, in valence quark models, the relativistic corrections to the SU(6) relation for the contribution of the electric dipole moments of the quarks to the electric dipole moment of the neutron can be expressed as a multiplicative correction factor. The correction factor is evaluated in light cone wavefunction models, in the bag model, and in relativistic mean-field models, and is found to lie between 1/3 and 1. It is also demonstrated that in these models, there is a linear relation between correction to the SU(6) value for g{sub A} and that for the electric dipole moment. 14 refs.
