Dissipation, hydrodynamics and the fireball
Sourendu Gupta
We investigate the hydrodynamics of the QCD plasma using dimensionless numbers built from the thermodynamics and transport theory of the plasma and characteristic dimensions of the…
Here's looking at you, fireball
Sourendu Gupta
Plasmas screen electromagnetic waves of frequency less than the plasma frequency, omega_p, with a skin depth, delta, specified by the electrical conductivity, sigma. Current estima…
Dimensional Reduction in High Temperature Gauge Theories
Saumen Datta, Sourendu Gupta
Screening masses in the equilibrium thermodynamics of gauge theories were measured. The spectroscopy of these screening masses gives strong evidence for dimensional reduction at $T…
Thermal Effects on Two-photon Decays of Pseudo-scalars
Sourendu Gupta, S. N. Nayak
We study the effect of finite temperatures and Fermion density on the effective pseudo-scalar-photon vertex induced by the triangle diagram. The manifestly covariant calculations s…
Collinear Divergences at One-loop Order for External Particles in a Heat-bath
Saumen Datta, Sourendu Gupta, V. Ravindran
In hard interactions between external particles incident on a heat-bath, we show that large logarithms are generated when a radiated or absorbed gauge boson is collinear with the i…
