  The supersymmetric Nambu-Jona-Lasinio model proposed by Cheng, Dai, Faisel
and Kong is re-analyzed by using an auxiliary superfield method in which a
hidden local U(1) symmetry emerges. It is shown that, in the healthy
field-space region where no negative metric particles appear, only SUSY
preserving vacua can be realized in the weak coupling regime and a composite
massive spin-1 supermultiplets appear as a result of spontaneous breaking of
the hidden local U(1) symmetry. In the strong coupling regime, on the other
hand, SUSY is dynamically broken, but it is always accompanied by negative
metric particles.
