Beta-functions for a SU(2) Matrix Model in 2 + epsilon Dimensions
Michaela Oswald, Robert D. Pisarski
To investigate the non-perturbative, electric sector of a deconfined gauge theory at nonzero temperature, we consider a SU(2) matrix model. We compute beta-functions to one loop or…
Gauge invariant effective action for the Polyakov line in the SU(N) Yang--Mills theory at high temperatures
Dmitri Diakonov, Michaela Oswald
We integrate out fast varying quantum fluctuations around static A_4 and A_i fields for the SU(N) gauge group. By assuming that the gluon fields are slowly varying but allowing for…
Covariant derivative expansion of fermionic effective action at high temperatures
Dmitri Diakonov, Michaela Oswald
We derive the fermionic contribution to the 1-loop effective action for A_4 and A_i fields at high temperatures, assuming that gluon fields are slowly varying but allowing for an a…
The kinetic energy for the static SU(2) Polyakov line
Michaela Oswald
At very high temperatures Yang--Mills theories can be described through perturbation theory. At the tree level the time components of the gluon fields decouple and yield a dimensio…
Covariant derivative expansion of Yang-Mills effective action at high temperatures
D. Diakonov, M. Oswald
Integrating out fast varying quantum fluctuations about Yang--Mills fields A_i and A_4, we arrive at the effective action for those fields at high temperatures. Assuming that the f…
