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…
Quantum gravity in a general background gauge
F. T. Brandt, J. Frenkel, D. G. C. McKeon
We deduce, in a general background gauge, the counter-term Lagrangian for pure quantum gravity to one-loop order. As an application, we evaluate the leading quantum correction to t…
Feynman diagrams in terms of on-shell propagators
F. T. Brandt, J. Frenkel, D. G. C. McKeon
It is shown that the usual expression for a Feynman diagram in terms of the Feynman propagator can be replaced by an equivalent expression involving the positive-energy…
On the analytically-improved running coupling in QCD
F. T. Brandt, J. Frenkel, D. G. C. McKeon +1
We examine, in the `t Hooft renormalization scheme, the analytic running coupling in QCD, using the two-loop -function with positive expansion parameters an…
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…
