P Renormalizability of Effective Scalar Field Theory
We present a comprehensive discussion of the consistency of the effective quantum field theory of a single Z2 symmetric scalar field. The theory is constructed from a bare Euclidean action which at a scale much greater than the particle’s mass is constrained only by the most basic requirements; stability, finiteness, analyticity, naturalness, and global symmetry. We prove to all orders in pertu...
متن کاملHalpern-Huang directions in effective scalar field theory
Halpern and Huang recently showed that there are relevant directions in the space of interactions at the Gaussian fixed point. I show that their result can be derived from Polchinski's form of the Wilson renormalization group. The derivation shows that the existence of these directions is independent of the cutoff function used.
متن کاملThe Decoupling Theorem in Effective Scalar Field Theory
We consider decoupling in the context of an effective quantum field theory of two scalar fields with well separated mass scales and a Z2 × Z2 symmetry. We first prove, using Wilson’s exact renormalization group equation, that the theory is renormalizable, in the same way that we showed in a previous paper that theories with a single mass scale were renormalizable. We then state and prove a deco...

متن کاملInfrared and Ultraviolet Behaviour of Effective Scalar Field Theory
We consider the infrared and ultraviolet behaviour of the effective quantum field theory of a single Z2 symmetric scalar field. In a previous paper we proved to all orders in perturbation theory the renormalizability of massive effective scalar field theory using Wilson’s exact renormalization group equation. Here we show that away from exceptional momenta the massless theory is similarly renor...
