Abstract: (arXiv)
We derive the constitutive equations of causal relativistic dissipative hydrodynamics (dd-hydrodynamics) from perfect nonextensive hydrodynamics (qq-hydrodynamics) using the nonextensive/dissipative correspondence (NexDC) proposed by us recently. The qq-hydrodynamics can be thus regarded as a possible model for the dd-hydrodynamics facilitating its application to high energy multiparticle production processes. As an example we have shown that applying the NexDC to the perfect 1+1 qq-hydrodynamics, one obtains a proper time evolution of the bulk pressure and the Reynolds number.
