Mean field approximation for effective theories of lattice QCD

open access: yes, 2022
For the exploration of the phase diagram of QCD, effective Polyakov loop theories derived from lattice QCD provide a valuable tool in the heavy quark mass regime.

NRQCD, Effective Field Theories and Potential Models [PDF]

open access: yes, 2000
We review some recent developments on non-relativistic effective field theories for heavy quark-antiquark systems and how they can bring a well founded connection between QCD and potential models.We review some recent developments on non-relativistic ...

Introduction to effective field theory [PDF]

open access: yesNuclear Physics A, 2001
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.

An Effective Field Theory for large oscillons

open access: yesJournal of High Energy Physics, 2022
Abstract We consider oscillons — localized, quasiperiodic, and extremely long-living classical solutions in models with real scalar fields. We develop their effective description in the limit of large size at finite field strength.

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 the protons.

Holographic effective field theories: a case study [PDF]

open access: yes, 2022
The identification of the low-energy effective field theory associated with a given microscopic strongly interacting microscopic theory constitutes a fundamental problem in theoretical physics, particularly challenging when the theory is not sufficiently

An Introduction to Effective Field Theory [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2007
This review summarizes effective field theory techniques, which are the modern theoretical tools for exploiting the existence of hierarchies of scale in a physical problem. The general theoretical framework is described and evaluated explicitly for a simple model. Power-counting results are illustrated for a few cases of practical interest, and several

Operator dimensions from moduli

open access: yesJournal of High Energy Physics, 2017
We consider the operator spectrum of a three-dimensional N = 2 $$ \mathcal{N}=2 $$ superconformal field theory with a moduli space of one complex dimension, such as the fixed point theory with three chiral superfields X, Y, Z and a superpotential W = XYZ.
