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

Effective field theory for leptoquarks
Journal of High Energy Physics, 2023 Leptoquarks enter in several extensions of the Standard Model as possible solutions to a number of observed anomalies. We work within the soft-collinear effective theory framework to present a detailed analysis of the decay rates of the three leptoquarks

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

Effective field theory approach to thermal bubble nucleation [PDF]
Physical 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.

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

The effective field theory of vector-tensor theories [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We investigate a systematic formulation of vector-tensor theories based on the effective field theory (EFT) approach. The input of our EFT is that the spacetime symmetry is spontaneously broken by the existence of a preferred timelike direction in ...
