Nonperturbative decoupling and effective field theory.
We examine recent claims that nonperturbative effects can prevent the decoupling of a heavy fermion whose mass arises from a Yukawa coupling to a scalar field. We show that in weakly coupled, four dimensional models such as the standard model with heavy mirror fermions the effects of the heavy fermions can always be accounted for by local operators involving light fields. We contrast this with ...
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 کاملIntroduction to Effective Field Theories * 1. Heisenberg–euler Effective Theory, Decoupling of Heavy Flavours
This is the first part of lectures about effective field theories. Decoupling of heavy-particle loops is considered (heavy leptons in QED, heavy quarks in QCD).
متن کاملOn Nonperturbative Solutions of Superstring Field Theory
Nonperturbative solutions to the nonlinear field equations in the NS sector of cubic as well as nonpolynomial superstring field theory can be obtained from a linear equation which includes a “spectral” parameter λ and a coboundary operator Q(λ). We borrow a simple ansatz from the dressing method (for generating solitons in integrable field theories) and show that classical superstring fields ca...
متن کاملNonperturbative calculational method in quantum field theory
An approximate procedure for performing nonperturbative calculations in quantum field theories is presented. The focus will be quantum non-Abelian gauge theories with the goal of understanding some of the open questions of these theories such as the confinement phenomenon and glueballs. One aspect of this nonperturbative method is the breaking down of the non-Abelian gauge group into smaller pi...
