Transversality of the logarithmic divergences in the Classical Finite Temperature SU(N) Self-Energy
A. Arrizabalaga, B. J. Nauta, Ch. G. van Weert
We show that the logarithmic divergences that appear in the classical approximation of the finite temperature SU(N) self-energy are transverse. We use the Ward identities in linear…
Divergences in Real-Time Classical Field Theories at Non-Zero Temperature
Gert Aarts, Bert-Jan Nauta, Chris G. van Weert
The classical approximation provides a non-perturbative approach to time-dependent problems in finite temperature field theory. We study the divergences in hot classical field theo…
Effective Classical Theory for Real-Time SU(N) Gauge Theories at High Temperature
B. J. Nauta, Ch. G. van Weert
We derive an effective classical theory for real-time SU() gauge theories at high temperature. By separating off and integrating out quantum fluctuations we obtain a 3D classica…
Real-time contour propagator for high temperature dimensional reduction
B. J. Nauta, Ch. G. van Weert
We discuss the extension of dimensional reduction in thermal field theory at high temperature to real-time correlation functions. It is shown that the perturbative corrections to t…
Transformations of real-time finite-temperature Feynman rules
M. A. van Eijck, R. Kobes, Ch. G. van Weert
We consider transformations of the propagator matrix in real-time finite-temperature field theory, resulting in transformed --point functions. As special cases of suc…
Temperature Dependence of the QCD Coupling
M. A. van Eijck, C. R. Stephens, Ch. G. van Weert
We present a one-loop calculation of a gauge invariant QCD beta function. Using both momentum and temperature renormalization group equations we investigate the running coupling in…
