Query: Relativistic Viscous Hydrodynamics for High Energy Heavy Ion Collisions   It has been over a decade since the first experimental data from gold nuclei
collisions at the Relativistic Heavy Ion Collider suggested hydrodynamic
behavior. While early ideal hydrodynamical models were surprisingly accurate in
their predictions, they ignored that the large longitudinal velocity gradient
meant that even small shear viscosity would produce large corrections to the
transverse dynamics. In addition, much less was known about the equation of
state predicted by lattice calculations of quantum chromodynamics, which
predicts a soft region as the degrees of freedom change from quarks to hadrons
but no first-order phase transition. Furthermore, the effects of late, dilute
stage rescattering were handled within the hydrodynamic framework to
temperatures where local kinetic equilibrium is difficult to justify. This
dissertation presents a three-dimensional viscous hydrodynamics code with a
realistic equation of state coupled consistently to a hadron resonance gas
calculation. The code presented here is capable of making significant
comparisons to experimental data as part of an effort to learn about the
structure of experimental constraints on the microscopic interactions of dense,
hot quark matter.
