Effective Field Theories and Lattice QCD [PDF]
Proceedings of The 8th International Workshop on Chiral Dynamics — PoS(CD15), 2015 I describe some of the many connections between lattice QCD and effective field theories, focusing in particular on chiral effective theory, and, to a lesser extent, Symanzik effective theory.

Introduction to Effective Field Theories in QCD [PDF]
AIP Conference Proceedings, 2002 We present a simple introduction to the techniques of effective field theory (EFT) and their application to QCD. For problems with more than one energy scale, the EFT approach is a useful alternative to more traditional model‐building strategies.

Uses of effective field theory in lattice QCD: Chapter 39 in At the Frontiers of Particle Physics, Handbook of QCD [PDF]
, 2002 Several physical problems in particle physics, nuclear physics, and astrophysics require information from non-perturbative QCD to gain a full understanding.

Effective field theories for QCD with rooted staggered fermions [PDF]
Physical Review D, 2007 Even highly improved variants of lattice QCD with staggered fermions show significant violations of taste symmetry at currently accessible lattice spacings.

Effective Field Theory and Lattice QCD approaches for hard probes in QCD matter [PDF]
Proceedings of International Conference on Hard and Electromagnetic Probes of High-Energy Nuclear Collisions — PoS(HardProbes2018), 2018 Hard Probes are an essential tool to discover the properties of the quark-gluon plasma created in heavy-ion collisions. The study of hard probes always involves taking into account very different energy scales, and this is precisely the situation in ...

Could reggeon field theory be an effective theory for QCD in the Regge limit? [PDF]
Journal of High Energy Physics, 2016 In this paper we investigate the possibility whether, in the extreme limit of high energies and large transverse distances, reggeon field theory might serve as an effective theory of high energy scattering for strong interactions.

Unraveling the Structure of Hadrons with Effective Field Theories of QCD [PDF]
, 2004 Effective Field theory is a powerful framework based on controlled expansions for problems with a natural separation of energy scales. This technique is particularly important for QCD, the theory of strong interactions, due to the vast diversity of phenomena that it describes.

Leading logs in QCD axion effective field theory [PDF]
Journal of High Energy Physics, 2021 Abstract The axion is much lighter than all other degrees of freedom introduced by the Peccei-Quinn mechanism to solve the strong CP problem. It is therefore natural to use an effective field theory (EFT) to describe its interactions. Loop processes calculated in the EFT may however explicitly depend on the ultraviolet cutoff.

Effective field theory for warm QCD [PDF]
Physical Review D, 2018 Using only global symmetries of QCD, we set up an effective model of quarks at finite temperature near the cross over, including all possible terms up to dimension 6. We first treat this in mean field theory. Then we investigate low-energy fluctuations around it up to one-loop order in fermions below the cross over.

Journal of High Energy Physics, 2023 We derive the causality and unitarity constraints on dimension 6 and dimension 8 Gluon field strength operators in the Standard Model Effective Field Theory (SMEFT). In the first part of the paper, we use the ‘amplitude analysis’ i.e. dispersion relation
