Bell violation in 2 ā 2 scattering in photon, gluon and graviton EFTs
Journal of High Energy Physics, 2023 In this paper, we explore Bell inequality violation for 2 ā 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
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 ...

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 is the Hubble scale at horizon exit.

Holographic Schwinger-Keldysh effective field theories
Journal 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.

Effective field theory of the deuteron with dibaryon fields [PDF]
Physical 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, $np \to dĪ³$, are calculated.

Derivation of effective field theories [PDF]
Physical 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

An Effective Field Theory for large oscillons
Journal of High Energy Physics, 2022 Abstract We consider oscillons ā localized, quasiperiodic, and extremely long-living classical solutions in models with real scalar fields. We develop their effective description in the limit of large size at finite field strength.
