Connected Green function approach to ground state symmetry breaking in -theory
J. M. Haeuser, W. Cassing, A. Peter +1
Using the cluster expansions for n-point Green functions we derive a closed set of dynamical equations of motion for connected equal-time Green functions by neglecting all connecte…
Braaten-Pisarski Method at Finite Chemical Potential
Hans Vija, Markus H. Thoma
The effective perturbation theory developed by Braaten and Pisarski for gauge theories at finite temperature is extended to finite chemical potential. As a first application the co…
Constraint Correlation Dynamics of SU(N) Gauge Theories
S. J. Wang, W. Cassing, J. M. Haeuser +2
A constraint correlation dynamics up to 4-point Green functions is proposed for SU(N) gauge theories which reduces the N-body quantum field problem to the two-body level. The resul…
Damping Rate of a Yukawa Fermion at Finite Temperature
Markus H. Thoma
The damping of a massless fermion coupled to a massless scalar particle at finite temperature is considered using the Braaten-Pisarski resummation technique. First the hard thermal…
Damping Rate of a Hard Photon in a Relativistic Plasma
Markus H. Thoma
The damping rate of a hard photon in a hot relativistic QED and QCD plasma is calculated using the resummation technique by Braaten and Pisarski.
