Renormalization and resummation in the O(N) model
arXiv:0811.2295 · doi:10.1016/j.nuclphysa.2009.01.064
Abstract
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 consistent perturbation theory at zero as well as at finite temperature with the help of momentum dependent renormalization schemes.
