Effective Action for Hard Thermal Loops in Gravitational Fields
R. R. Francisco, J. Frenkel, J. C. Taylor
We examine, through a Boltzmann equation approach, the generating action of hard thermal loops in the background of gravitational fields. Using the gauge and Weyl invariance of the…
On the gauge independence of the fermion pole mass
Ashok K. Das, R. R. Francisco, J. Frenkel
We study the question of complete gauge independence of the fermion pole mass by choosing a general class of gauge fixing which interpolates between the covariant, the axial and th…
Hard thermal loops in long wave-length and static external gravitational fields
R. R. Francisco, J. Frenkel
We study, in the long wave-length and static limits, the structure of the n-point graviton functions at high temperature. Using the gauge and Weyl invariance of the theory, we deri…
Causal amplitudes in the Schwinger model at finite temperature
Ashok Das, R. R. Francisco, J. Frenkel
We show, in the imaginary time formalism, that the temperature dependent parts of all the retarded (advanced) amplitudes vanish in the Schwinger model. We trace this behavior to th…
