Query: Multiplicity Dependence of Partially Coherent Pion Production in
  Relativistic Heavy Ion Collisions   We investigate two- and three-particle intensity correlation functions of
pions in relativistic heavy ion collisions for different colliding energies.
Based on three models of particle production, we analyze the degree to which
the pion sources are chaotic in the SPS S+Pb, Pb+Pb and the RHIC Au+Au
collisions. The ``chaoticity'', $\lambda$, of the two-particle correlation
functions is corrected for long-lived resonance decays. The effect of the
partial Coulomb correction is also examined. Although the partially coherent
model gives a result which is consistent with that of STAR, the chaotic
fraction does not exhibit clear multiplicity dependence if we take into account
both the corrected chaoticity and the weight factor of the three-pion
correlation function.
  The result of the partially-multicoherent model indicates an increasing
number of coherent sources in higher multiplicity events.
