Effective field theory [PDF]

open access: yes, 1995
I give a brief review of effective field theory, disscussing the contribution of Feza G\"ursey in particular and focusing on the literature I am most familiar with.Comment: 17 pages, no figs, macros appended, plain ...

Introduction to Effective Field Theory [PDF]

open access: yesNuclear Physics A, 2000
An introduction to methods of effective field theory is given. Examples are presented, including Rayleigh scattering from nonrelativistic quantum mechnics, chiral perturbation theory/QCD as well as electromagnetic and weak interactions of nucleons ...

Effective field theory of 3He [PDF]

open access: yesFew-Body Systems, 2010
3He and the triton are studied as three-body bound states in the effective field theory without pions. We study 3He using the set of integral equations developed by Kok et al. which includes the full off-shell T-matrix for the Coulomb interaction between

Effective Beta-Functions for Effective Field Theory [PDF]

open access: yesJournal of High Energy Physics, 2001
We consider the problem of determining the beta-functions for any reduced effective field theory. Even though not all the Green's functions of a reduced effective field theory are renormalizable, unlike the full effective field theory, certain effective ...

Extremal effective field theories [PDF]

open access: yesJournal of High Energy Physics, 2021
Abstract Effective field theories (EFT) parameterize the long-distance effects of short-distance dynamics whose details may or may not be known. Previous work showed that EFT coefficients must obey certain positivity constraints if causality and unitarity are satisfied at all scales.

Causal effective field theories

open access: yesPhysical Review D, 2022
Physical principles such as unitarity, causality, and locality can constrain the space of consistent effective field theories (EFTs) by imposing two-sided bounds on the allowed values of Wilson coefficients. In this paper, we consider the bounds that arise from the requirement of low-energy causality alone, without appealing to any assumptions about UV

Effective field theories [PDF]

open access: yes, 2008
These lectures introduce some of the basic notions of effective field theories, as used in particle physics. The topics discussed are the $ S=1$ and $ S =2$ weak interactions, and chiral perturbation theory as applied to mesons, baryons, and hadrons containing heavy quarks.

Holographic effective field theories [PDF]

open access: yesJournal of High Energy Physics, 2016
We derive the four-dimensional low-energy effective field theory governing the moduli space of strongly coupled superconformal quiver gauge theories associated with D3-branes at Calabi-Yau conical singularities in the holographic regime of validity. We use the dual supergravity description provided by warped resolved conical geometries with mobile D3 ...

Effective Field Theories [PDF]

open access: yesParticles, 2020
This paper represents a pedagogical introduction to low-energy effective field theories. In some of them, heavy particles are “integrated out” (a typical example—the Heisenberg–Euler EFT); in some, heavy particles remain but some of their degrees of freedom are “integrated out” (Bloch–Nordsieck EFT).
