DIPOLE-MOMENTS OF THE RHO-MESON

The electric and magnetic dipole moments of the rho meson are calculat ed using the propagators and vertices derived from the QCD Dyson-Schwi nger equations. Results obtained from using the Bethe-Salpeter amplitu de studied by Chappell, Mitchell, and Tandy, and Pichowsky and Lee, ar e compared. The rho meson electric dipole moment is generated through the inclusion of a quark electric dipole moment, which is left as a fr ee variable. These results are compared to the perturbative results to obtain a measure of the effects of quark interactions and confinement . The two dipole moments are also calculated using the phenomenologica l MIT bag model to provide a further basis for comparison. [S0556-2813 (98)01405-8].
