Dimension-8 operators in the Standard Model Effective Field Theory [PDF]

open access: yesJournal of High Energy Physics, 2020
We present a complete basis of dimension-8 operators in the Standard Model Effective Field Theory. Attention is paid to operators that vanish in the absence of flavor structure. The 44,807 operators are encoded in 1,031 Lagrangian terms.

Spinning black hole binary dynamics, scattering amplitudes, and effective field theory [PDF]

open access: yesPhysical Review D, 2020
We describe a systematic framework for finding the conservative potential of compact binary systems with spin based on scattering amplitudes of particles of arbitrary spin and effective field theory.

Top, Higgs, diboson and electroweak fit to the Standard Model effective field theory [PDF]

open access: yesJournal of High Energy Physics, 2020
The search for effective field theory deformations of the Standard Model (SM) is a major goal of particle physics that can benefit from a global approach in the framework of the Standard Model Effective Field Theory (SMEFT).

Dark sector effective field theory

open access: yesJournal of High Energy Physics, 2023
We introduce the effective field theory of two different light dark particles interacting with the standard model (SM) light states in a single vertex, termed dark sector effective field theory (DSEFT). We focus on the new light particles with spin up to

Post-Minkowskian effective field theory for conservative binary dynamics [PDF]

open access: yesJournal of High Energy Physics, 2020
We develop an Effective Field Theory (EFT) formalism to solve for the conservative dynamics of binary systems in gravity via Post-Minkowskian (PM) scattering data. Our framework combines a systematic EFT approach to compute the deflection angle in the PM

Complete set of dimension-eight operators in the standard model effective field theory [PDF]

open access: yesPhysical Review D, 2020
We present a complete list of the dimension 8 operator basis in the standard model effective field theory using group theoretic techniques in a systematic and automated way.

DsixTools 2.0: the effective field theory toolkit [PDF]

open access: yesThe European Physical Journal C, 2020
DsixTools is a Mathematica package for the handling of the standard model effective field theory (SMEFT) and the low-energy effective field theory (LEFT) with operators up to dimension six, both at the algebraic and numerical level.

Effective field theory approach to thermal bubble nucleation [PDF]

open access: yesPhysical Review D, 2021
The standard vacuum bounce formalism suffers from inconsistencies when applied to thermal bubble nucleation, for which ad hoc workarounds are commonly adopted.

Conservative Dynamics of Binary Systems to Third Post-Minkowskian Order from the Effective Field Theory Approach. [PDF]

open access: yesPhysical Review Letters, 2020
We derive the conservative dynamics of nonspinning binaries to third post-Minkowskian order, using the effective field theory (EFT) approach introduced in [G. Kälin and R. A. Porto, J. High Energy Phys. 11 (2020) 106JHEPFG1029-847910.1007/JHEP11(2020)106]

Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory [PDF]

open access: yesFortschritte der Physik, 2021
We continue our study of effective field theory via homotopy transfer of L∞$L_\infty$ ‐algebras, and apply it to tree‐level non‐Wilsonian effective actions of the kind discussed by Sen in which the modes integrated out are comparable in mass to the modes
