Query: Soft Physics in STAR   The STAR Experiment at RHIC is well-suited to making measurements of particle
yields from relativistic nuclear collisions in the low transverse momentum, or
"soft", regime. We present preliminary results on measurements of pion (0,-,+),
kaon (-,+,0short), rho, K*0 + anti-K*0, f0, proton, antiproton, phi, Lambda,
anti-Lambda, Xi, anti-Xi, Omega, and anti-Omega from the first two years of
physics running at RHIC. An abundance of physics topics can be addressed by
these measurements, some of which are discussed here along with the results.
