Resumen:
We present an unquenched quark model calculation of the mass shifts of
ground-state octet and decuplet baryons due to the coupling to the
meson-baryon continuum. All ground-state baryons and pseudoscalar mesons
are included in our calculation as intermediate states. The q (q) over
bar pair creation effects are taken explicitly into account through a
microscopic, QCD-inspired, quark-antiquark pair creation mechanism.
