Abstract
A generalized strangeness-including statistical bootstrap model
(SSBM) is
constructed so as to include
independent fugacities for up and down quarks. Such an extension
is crucial
for the confrontation of multiparticle data emerging from heavy
ion
collisions, wherein isospin symmetry is not satisfied. Two constraints,
in
addition to the presence of a critical surface which sets the
boundaries of the
hadronic world, enter the extended model. An analysis pertaining
to
produced particle multiplicities and ratios is performed
for the
S+Ag interaction at 200GeV/nucleon. The
resulting
evaluation, concerning the location of the source of the produced
system,
is slightly in favor of the source being outside the hadronic
domain.
