What is the Geometry of Effective Field Theories? / Cohen, Timothy (CERN ; EPFL, Lausanne, LPTP ; Oregon U.) ; Lu, Xiaochuan (UC, San Diego (main)) ; Zhang, Zhengkang (U. Utah, Salt Lake City)
We elaborate on a recently proposed geometric framework for scalar effective field theories. [...]

Anomaly Cancellation in Effective Field Theories From the Covariant Derivative Expansion / Cohen, Timothy (CERN ; EPFL, Lausanne, LPTP ; Oregon U.) ; Lu, Xiaochuan (Oregon U. ; UC, San Diego) ; Zhang, Zhengkang (UC, Santa Barbara)
We extend our recently-proposed formalism for calculating anomalies of global and gauge symmetries using the Covariant Derivative Expansion to include a general class of operators that can appear in relativistic Effective Field Theories (EFTs). This allows us to prove that EFT operators involving general scalar, vector, and tensor couplings to fermion bilinears only give rise to irrelevant anomalies, which can be removed by an appropriate choice of counterterms, thereby confirming the absence of new constraints from anomaly cancellation on the Standard Model EFT..

Anomalies From the Covariant Derivative Expansion / Cohen, Timothy (CERN ; EPFL, Lausanne, LPTP ; Oregon U.) ; Lu, Xiaochuan (Oregon U. ; UC, San Diego) ; Zhang, Zhengkang (UC, Santa Barbara)
We revisit the calculation of anomalies for global and gauge symmetries in the framework of the Covariant Derivative Expansion (CDE). Due to the presence of UV divergences, the result is an ambiguous quantity that depends on the regularization procedure and the renormalization scheme. [...]

Precision matching of microscopic physics to the Standard Model Effective Field Theory (SMEFT) / Greljo, Admir (Universitaet Bern (CH)) ; Dawson, Sally (Department of Physics, Brookhaven National Laboratory (US)) ; Lohwasser, Kristin (University of Sheffield (GB)) ; Aebischer, Jason (Universität Zürich (CH)) ; Das Bakshi, Supratim (Universidad de Granada (ES)) ; Carmona, Adrían (Universidad de Granada (ES)) ; Chakrabortty, Joydeep (Indian Institute of Technology Kanpur (IN)) ; Cohen, Timothy (University of Oregon (US)) ; Criado, Juan Carlos (Durham University (UK)) ; Fuentes-Martín, Javier (Universidad de Granada (ES)) et al.
This note gives an overview of the tools for the precision matching of ultraviolet theories to the Standard Model effective field theory (SMEFT) at the tree level and one loop. Several semi- and fully automated codes are presented, as well as some supplementary codes for the basis conversion and the subsequent running and matching at low energies. [...]

The Fermionic Universal One-Loop Effective Action / Ellis, Sebastian A.R. (SLAC) ; Quevillon, Jérémie (LPSC, Grenoble) ; Vuong, Pham Ngoc Hoa (LPSC, Grenoble) ; You, Tevong (CERN ; Cambridge U., DAMTP ; Cambridge U.) ; Zhang, Zhengkang (Caltech)
Recent development of path integral matching techniques based on the covariant derivative expansion has made manifest a universal structure of one-loop effective Lagrangians. The universal terms can be computed once and for all to serve as a reference for one-loop matching calculations and to ease their automation. [...]
