Abstract
Within a relativistic hydrodynamic framework, we use four
different equations of state of nuclear matter to compare to
experimental spectra from CERN/SPS experiments NA44 and
NA49. Freeze-out hypersurfaces and Bose-Einstein correlation
functions for identical pion pairs are discussed. We find that
two-pion Bose-Einstein interferometry measures the relationship
between the temperature and the energy density in the equation of
state during the late hadronic stage of the fireball expansion. Little
sensitivity of the light-hadron data to a quark-gluon plasma
phase-transition is seen.
