Renormalization and resummation in the O(N) model
A. Jakovac
In the O(N) model for the large N expansion one needs resummation which makes the renormalization of the model difficult. In the paper it is discussed, how can one perform a consis…

Shear viscosity of pure Yang-Mills theory at strong coupling
Antal Jakovac, Daniel Nogradi
We calculate the shear viscosity to entropy density ratio in pure SU(N) Yang-Mills theory below the critical temperature using the strong coupling expansion. The result for the eta…

Renormalization of O(N) model in 1/N expansion in auxiliary field formalism
A. Jakovac
We study the renormalization of the O(N) model using the auxiliary field formalism (Hubbard-Stratonovich transformation) in the 1/N expansion at finite temperature. We provide the…
