Self-consistent solitonic solutions with baryon number one are obtaine
d in the chiral quark sigma model. The translational invariant vacuum
is stabilized by a Landau ghost subtraction procedure based on the req
uirement of the Kallen-Lehman (KL) representation for the meson propag
ators. The connection of this ghost free model (KL model) to the more
popular Nambu-Jona-Lasinio (NJL) model is discussed in detail.
