RG equations and high energy behaviour in non-renormalizable theories

We suggest a novel view on non-renormalizable interactions. It is based on the usual BPHZ R-operation which is equally applicable to any local QFT independently of whether it is renormalizable or not. As a playground we take the ϕD4 theory in D dimensions for D=4,6,8,10 and consider the four-point s...
