On the development of effective field theory [PDF]

open access: yesThe European Physical Journal H, 2021
AbstractEditor’s note: One of the most important developments in theoretical particle physics at the end of the 20th century and beginning of the twenty-first century has been the development of effective field theories (EFTs). Pursuing an effective field theory approach is a methodology for constructing theories, where a set of core principles is ...

Bell violation in 2 → 2 scattering in photon, gluon and graviton EFTs

open access: yesJournal of High Energy Physics, 2023
In this paper, we explore Bell inequality violation for 2 → 2 scattering in Effective Field Theories (EFTs) of photons, gluons, and gravitons. Using the CGLMP Bell parameter (I 2), we show that, starting from an appropriate initial non-product state, the

Effective field theories and inflationary magnetogenesis

open access: yesPhysics 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 ...

Effective field theories and inflation [PDF]

open access: yesJournal 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 is the Hubble scale at horizon exit.

Holographic Schwinger-Keldysh effective field theories

open access: yesJournal of High Energy Physics, 2019
We construct a holographic dual of the Schwinger-Keldysh effective action for the dissipative low-energy dynamics of relativistic charged matter at strong coupling in a fixed thermal background.

Derivation of effective field theories [PDF]

open access: yesPhysical Review E, 2008
A general self-consistency approach allows a thorough treatment of the corrections to the mean-field approximation (MFA). The natural extension of standard MFA with the help of a cumulant expansion leads to a new point of view on the effective field theories. The proposed approach can be used for a systematic treatment of fluctuation effects of various

Effective field theory of the deuteron with dibaryon fields [PDF]

open access: yesPhysical Review C, 2005
Pionless effective field theory with dibaryon fields is reexamined for observables involving the deuteron. The electromagnetic form factors of the deuteron and the total cross sections of radiative neutron capture on the proton, $np \to dγ$, are calculated.

Holographic effective field theories and the AdS_4/CFT_3 correspondence [PDF]

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