  The self-energies of the full set of flavor SU(3) octet and decuplet baryons
are computed within a relativistic chiral effective theory framework. The
leading nonanalytic chiral behavior is derived for the octet and decuplet
masses, and a finite-range regularization consistent with Lorentz and gauge
invariance is applied to account for the finite size of the baryons. Using a
four-dimensional dipole form factor, the relative importance of various
meson-baryon loop contributions to the self-energies is studied numerically as
a function of the dipole range parameter and meson mass, and comparison is made
between the relativistic results and earlier approximations within the heavy
baryon limit.
