RGfactorization
RGfactorization refers to a factorization technique used in quantum field theory, specifically within the context of renormalization group flows. It's a method for disentangling different scales or energy regimes in a quantum field theory. The core idea is to express a theory at a given energy scale in terms of an "effective" theory at a lower energy scale. This effective theory captures the essential physics of the higher energy modes that have been integrated out.
RGfactorization often involves splitting a complicated theory into simpler, more manageable components. One part might represent
