Query: Causal Baryon Diffusion and Colored Noise for Heavy Ion Collisions   We construct a model for baryon diffusion which has the desired properties of
analyticity and causality. The model also has the desired property that the
noise correlation function is not a Dirac delta function in space and time. The
model depends on three time constants in addition to the diffusion constant.
This description can be incorporated into 2nd order viscous hydrodynamical
models of heavy ion collisions.
