Thermal quantum gravity in a general background gauge
F. T. Brandt, J. Frenkel, D. G. C. McKeon +1
We calculate in a general background gauge, to one-loop order, the leading logarithmic contribution from the graviton self-energy at finite temperature , extending a previous an…
Loop corrections in a solvable UV-finite model and its effective field theory
F. T. Brandt, J. Frenkel, D. G. C. McKeon +1
We examine some features of the non-renormalizability induced through the use of low-energy effective Lagrangians in loop diagrams, in the context of a scalar model which is ultrav…
Forward scattering amplitudes in the imaginary time formalism
F. T. Brandt, J. Frenkel, S. Martins-Filho +2
We study, in the imaginary time formalism, the relation between loops and on-shell forward scattering tree amplitudes in thermal field theories. This allows for an efficient evalua…
First order formulation of the Yang-Mills theory in a background field
F. T. Brandt, J. Frenkel, D. G. C. McKeon
The background gauge renormalization of the first order formulation of the Yang-Mills theory is studied by using the BRST identities. Together with the background symmetry, these i…
Induced magnetic moment for a spinless charged particle in the thin-layer approach
F. T. Brandt, J. A. Sánchez-Monroy
We determine the effective dynamics for a spinless charged particle, in the presence of electromagnetic fields, constrained to a space curve. We employ the thin-layer procedure and…
QED plasma in a background of static gravitational fields
F. T. Brandt, J. Frenkel, J. B. Siqueira
We obtain the effective Lagrangian of static gravitational fields interacting with a QED plasma at high temperature. Using the equivalence between the static hard thermal loops and…
