Effective Field Theories [PDF]

, 1992
Effective field theories encode the predictions of a quantum field theory at low energy. The effective theory has a fairly low ultraviolet cutoff.

Renormalons in Effective Field Theories [PDF]

Physical Review D, 1994
We investigate the high-order behavior of perturbative matching conditions in effective field theories. These series are typically badly divergent, and are not Borel summable due to infrared and ultraviolet renormalons which introduce ambiguities in ...

Effective Field Theories and Inflation [PDF]

Journal of Cosmology and Astroparticle Physics, 2003
We investigate the possible influence of very-high-energy physics on inflationary predictions focussing on whether effective field theories can allow effects which are parametrically larger than order H^2/M^2, where M is the scale of heavy physics and H ...

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

Firewall from Effective Field Theory [PDF]

Universe, 2021
For an effective field theory in the background of an evaporating black hole with spherical symmetry, we consider non-renormalizable interactions and their relevance to physical effects. The background geometry is determined by the semi-classical Einstein equation for an uneventful horizon where the vacuum energy–momentum tensor is small for freely ...

Effective field theories and inflationary magnetogenesis

Physics Letters B, 2021
The effective approach is applied to the analysis of inflationary magnetogenesis. Rather than assuming a particular underlying description, all the generally covariant terms potentially appearing with four space-time derivatives in the effective action ...

Hidden Conformal Invariance of Scalar Effective Field Theories [PDF]

, 2020
We argue that conformal invariance is a common thread linking several scalar effective field theories that appear in the double copy and scattering equations.
