Constraining Effective Field Theories with Machine Learning. [PDF]
Physical Review Letters, 2018 We present powerful new analysis techniques to constrain effective field theories at the LHC. By leveraging the structure of particle physics processes, we extract extra information from Monte Carlo simulations, which can be used to train neural network ...

Effective field theories with instantons [PDF]
Nuclear Physics B, 1994 We explain how nonperturbative effects can be systematically included when constructing an effective field theory. We concentrate in particular on the matching calculation, by which a low energy theory without a heavy particle degree of freedom is matched onto the full theory.

Effective field theories as Lagrange spaces
Journal of High Energy Physics, 2023 We present a formulation of scalar effective field theories in terms of the geometry of Lagrange spaces. The horizontal geometry of the Lagrange space generalizes the Riemannian geometry on the scalar field manifold, inducing a broad class of affine ...

Effective Field Theory of 3He [PDF]
Few-Body Systems, 2010 3He and the triton are studied as three-body bound states in the effective field theory without pions. We study 3He using the set of integral equations developed by Kok et al. which includes the full off-shell T-matrix for the Coulomb interaction between the protons.

Journal of Cosmology and Astroparticle Physics, 2020 During inflation, there is a preferred reference frame in which the expansion of the background spacetime is spatially isotropic. In contrast to Minkowski spacetime, observables can depend on the velocity of the system with respect to this cosmic rest ...

A Comment on Effective Field Theories of Flux Vacua [PDF]
Fortschritte der Physik, 2018 We discuss some basic aspects of effective field theory applied to supergravity theories which arise in the low‐energy limit of string theory. Our discussion is particularly relevant to the effective field theories of no‐scale supergravities that break ...

Amplitude/operator basis in chiral perturbation theory
Journal of High Energy Physics, 2023 We establish a systematic construction of the on-shell amplitude/operator basis for Chiral Perturbation Theory (ChPT) in D = 4 spacetime dimensions and with an arbitrary number of flavors N f .

Constructing effective field theories via their harmonics [PDF]
Physical Review D, 2019 We consider the construction of operator bases for massless, relativistic quantum field theories, and show this is equivalent to obtaining the harmonic modes of a physical manifold (the kinematic Grassmannian), upon which observables have support.

Effective field theories for heavy quarkonium [PDF]
, 2004 We review recent theoretical developments in heavy quarkonium physics from the point of view of Effective Field Theories of QCD. We discuss Non-Relativistic QCD and concentrate on potential Non-Relativistic QCD.
