Dissipative hydrodynamic evolution of hot quark matter at finite baryon density
High-energy heavy ion collider experiments at RHIC and LHC have revealed that
relativistic hydrodynamic models describe the hot and dense quark matter
quantitatively. In this study, I develop a novel dissipative hydrodynamic model
at finite baryon density to investigate the net baryon rapidity distribution.
The results show that the distribution is widened in hydrodynamic evolution,
which implies that the transparency of the collisions is effectively enhanced.
This suggests that the kinetic energy loss for medium production at the initial
stage could be larger. Furthermore, the net baryon distribution is found
sensitive to baryon diffusion, implying that dissipative hydrodynamic modeling
would be important for understanding the hot medium.Comment: 8 pages, 5 figures - To appear in the conference proceedings for
