Event Generation from Effective Field Theory [PDF]
, 2006 A procedure is developed for using Soft Collinear Effective Theory (SCET) to generate fully exclusive events, which can then be compared to data from collider experiments.

Halo Effective Field Theory of 6He
EPJ Web of Conferences, 2016 6He has a cluster structure with a tight 4He (α) core surrounded by two loosely bound neutrons (n) making it a halo nucleus. The leading-order (LO) Halo Effective Field Theory (EFT) [1, 2] calculations using momentum-space Faddeev equations pertinent to ...

The geometric Standard Model Effective Field Theory
Journal of High Energy Physics, 2020 We develop the geometric formulation of the Standard Model Effective Field Theory (SMEFT). Using this approach we derive all-orders results in the 2 H † H / Λ $$ \sqrt{2\left\langle {H}^{\dagger }H\right\rangle }/\Lambda $$ expansion relevant for studies

Effective field theory for hydrodynamics without boosts
SciPost Physics, 2021 We formulate the Schwinger-Keldysh effective field theory of hydrodynamics without boost symmetry. This includes a spacetime covariant formulation of classical hydrodynamics without boosts with an additional conserved particle/charge current coupled to ...

A comment on effective field theories of flux vacua [PDF]
, 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 supersymmetry, including those that appear in constructing de Sitter solutions of string theory.

Conformal bootstrap at large charge
Journal of High Energy Physics, 2018 We consider unitary CFTs with continuous global symmetries in d > 2. We consider a state created by the lightest operator of large charge Q ≫ 1 and analyze the correlator of two light charged operators in this state.

Introduction to Effective Field Theory [PDF]
Annual Review of Nuclear and Particle Science, 2007 Using examples from across the sub-disciplines of physics, this introduction shows why effective field theories are the language in which physical laws are written. The tools of effective field theory are demonstrated using worked examples from areas including particle, nuclear, atomic, condensed matter and gravitational physics.

The effective action of double field theory [PDF]
Journal of High Energy Physics, 2011 We perform a generalized Scherk-Schwarz dimensional reduction of Double Field Theory on a twisted double torus. The four dimensional effective action is shown to exactly reproduce the bosonic electric sector of gauged N = 4 supergravity. We present explicit expressions for the gaugings in terms of the twists, and analyze the associated string ...

CP-violating axion interactions in effective field theory
Journal of High Energy Physics, 2022 Axions are introduced to explain the observed smallness of the θ ¯ $$ \overline{\theta} $$ term of QCD. Standard Model extensions typically contain new sources of CP violation, for instance to account for the baryon asymmetry of the universe.

Effective Lagrangians for Scalar Fields and Finite Size Effects in Field Theory [PDF]
J.Math.Phys.45:179-196,2004, 2002 We discuss the approach of effective field theory on a d-dimensional Euclidean space in a scalar theory with two different mass scales in the presence of flat surfaces. Then considering Dirichlet and Neumann boundary conditions, we implement the renormalization program in the lambda phi^{4} theory in a region bounded by two parallel hyperplanes in the ...
