Constraints on the model from a negative number of flavors
Daniele Artico, Jasper Roosmale Nepveu
Treating the number of flavors as a variable in the model leads to non-perturbative constraints on the spectrum of operators. Using the duality between and $Sp(-n…
Two-loop renormalization of general bosonic effective field theories
Guilherme Guedes, Jasper Roosmale Nepveu
The renormalization of higher-dimensional operators in quantum field theory is essential for phenomenological analyses in particle physics, and plays a significant role in the stud…
EFT meets CFT: Multiloop renormalization of higher-dimensional operators in general theories
Johan Henriksson, Stefanos R. Kousvos, Jasper Roosmale Nepveu
The renormalization of composite operators is a fundamental aspect of quantum field theory, relevant for the description of phase transitions and high energy phenomenology. We calc…
Multi-loop spectra in general scalar EFTs and CFTs
Johan Henriksson, Franz Herzog, Stefanos R. Kousvos +1
We consider the most general effective field theory (EFT) Lagrangian with scalar fields and derivatives, and renormalise it to substantially higher loop order than existing results…
Positivity in the Renormalization of Effective Field Theory
You-Peng Liao, Jasper Roosmale Nepveu, Chia-Hsien Shen
We show that the direction of renormalization in effective field theory is constrained by fundamental principles in the infrared$\unicode{x2014}$unitarity, analyticity, and Lorentz…
A log story short: running contributions to radiative Higgs decays in the SMEFT
Christophe Grojean, Guilherme Guedes, Jasper Roosmale Nepveu +1
We investigate the renormalization of the radiative decays of the Higgs to two gauge bosons in the Standard Model Effective Field Theory at mass dimension eight. Given that these a…
Field Redefinitions and Infinite Field Anomalous Dimensions
Aneesh V. Manohar, Julie Pagès, Jasper Roosmale Nepveu
Field redefinitions are commonly used to reduce the number of operators in the Lagrangian by removing redundant operators and transforming to a minimal operator basis. We give a ge…
Higher-derivative relations between scalars and gluons
Quentin Bonnefoy, Gauthier Durieux, Jasper Roosmale Nepveu
We extend the covariant color-kinematics duality introduced by Cheung and Mangan to effective field theories. We focus in particular on relations between the effective field theori…
Non-linear non-renormalization theorems
Weiguang Cao, Franz Herzog, Tom Melia +1
We study the mixing of operators under renormalization group flow in quantum theories, and prove a non-renormalization theorem at non-linear order. It dictates zeros up to a certai…
Theoretical developments in the SMEFT at dimension-8 and beyond
Simone Alioli, Radja Boughezal, Weiguang Cao +24
In this contribution to the Snowmass 2021 process we review theoretical developments in the Standard Model Effective Field Theory (SMEFT) with a focus on effects at the dimension-8…
The seeds of EFT double copy
Quentin Bonnefoy, Gauthier Durieux, Christophe Grojean +2
We explore the double copy of effective field theories (EFTs), in the recently proposed generalized color-kinematics and Kawai-Lewellen-Tye (KLT) approaches. In the former, we syst…
Renormalization and non-renormalization of scalar EFTs at higher orders
Weiguang Cao, Franz Herzog, Tom Melia +1
We renormalize massless scalar effective field theories (EFTs) to higher loop orders and higher orders in the EFT expansion. To facilitate EFT calculations with the R* renormalizat…
