A bstract We calculate P (k⊥), the probability distribution for an energetic parton that
propagates for a distance L through a medium without radiating to pick up transverse …

Inspired by recent progress on classical limits of scattering amplitudes, we show that hard
thermal loops can be obtained from classical limits of off-shell currents. The classicality of …

In this paper, we give a simple diagrammatic identification of the unique combination of the
causal n-point vertex functions in the real time formalism that would coincide with the …

An often used rule that the thermal correction to the self-energy is the thermal phase-space
times the forward scattering amplitude from target particles is shown to be the leading term …

We study the behavior of the photon two point function, in noncommutative QED, in a
general covariant gauge and in arbitrary space-time dimensions. We show, to all orders, that …

We study the graviton self-energy function in a general gauge, using a hard thermal loop
expansion which includes terms proportional to T 4, T 2 and log (T). We verify explicitly the …

We study the running of the QCD coupling with the momentum squared (Q²) and the
temperature scales in the high temperature limit (T> Tc), using a mass dependent …

We study the parity-breaking terms generated by the box diagram in (2+ 1)-dimensional
thermal QED. These lead, in the long wave limit, to a gauge invariant extensive action, which …

In the context of the imaginary-time formalism for scalar thermal field theory, it is shown that
the result of performing the summations over Matsubara frequencies associated with loop …

In this paper, we extend our earlier one loop analysis to two loops and give a simple
diagrammatic description for the retarded Green's functions at finite temperature in terms of …
