Extremal effective field theories [PDF]

Journal 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.

Whence the Effectiveness of Effective Field Theories? [PDF]

The British Journal for the Philosophy of Science, 2017
Effective quantum field theories are effective insofar as they apply within a prescribed range of length-scales, but within that range they predict and describe with extremely high accuracy and precision.

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.

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 ...

The Bases of Effective Field Theories [PDF]

Nuclear Physics B, 2013
With reference to the equivalence theorem, we discuss the selection of basis operators for effective field theories in general. The equivalence relation can be used to partition operators into equivalence classes, from which inequivalent basis operators ...

On the Power Counting in Effective Field Theories [PDF]

Physics Letters B, 2013
We discuss the systematics of power counting in general effective field theories, focussing on those that are nonrenormalizable at leading order. As an illuminating example we consider chiral perturbation theory gauged under the electromagnetic $U(1 ...

Dilaton Effective Field Theory [PDF]

Universe, 2022
We review and extend recent studies of dilaton effective field theory (dEFT) that provide a framework for the description of the Higgs boson as a composite structure. We first describe the dEFT as applied to lattice data for a class of gauge theories with near-conformal infrared behavior.
