Stress tensor and bulk viscosity in relativistic nuclear collisions
(American Physical Society, 2008)
We discuss the influence of different initial conditions for the stress tensor and the effect of bulk viscosity on the expansion and cooling of the fireball created in relativistic heavy ion collisions. In particular, we ...
Photon bremsstrahlung and diffusive broadening of a hard jet
(American Physical Society, 2008)
The photon bremsstrahlung rate from a quark jet produced in deep-inelastic scattering (DIS) off a large nucleus is studied in the collinear limit. The leading medium-enhanced higher twist corrections that describe the ...
