Extremal effective field theories [PDF]

Journal of High Energy Physics, 2021
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 ...

Effective Field Theories [PDF]

Particles, 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 ...

Computing tools for effective field theories [PDF]

European Physical Journal C: Particles and Fields
In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics.

Entanglement and effective field theories

Physics Letters B
We investigate the emergence of geometric phases in chiral transformations within gauge theories coupled to fermions. We begin by analyzing the Schwinger model in (1+1) dimensions, where chiral symmetry is explicitly modified due to the dynamical ...

Effective field theories in R ξ gauges [PDF]

Journal of High Energy Physics, 2019
In effective quantum field theories, higher dimensional operators can affect the canonical normalization of kinetic terms at tree level. These contributions for scalars and gauge bosons should be carefully included in the gauge fixing procedure, in order

Causal effective field theories

Physical 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]

, 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.

Constructing operator basis in supersymmetry: a Hilbert series approach

Journal of High Energy Physics, 2023
In this paper we introduce a Hilbert series approach to build the operator basis for a N = 1 supersymmetry theory with chiral superfields. We give explicitly the form of the corrections that remove redundancies due to the equations of motion and ...

Holographic effective field theories [PDF]

Journal 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 ...
