In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In order to discuss present and future prospects concerning automated tools in this field, the SMEFT-Tools 2022 workshop was held at the University of Zurich from 14th-16th September 2022. [...]

Towards a Muon Collider
/ Accettura, Carlotta (CERN) ; Adams, Dean (Rutherford) ; Agarwal, Rohit (UC, Berkeley (main)) ; Ahdida, Claudia (CERN) ; Aimè, Chiara (Pavia U. ; INFN, Pavia) ; Amapane, Nicola (INFN, Turin ; Turin U.) ; Amorim, David (CERN) ; Andreetto, Paolo (INFN, Padua) ; Anulli, Fabio (INFN, Rome) ; Appleby, Robert (Manchester U.) et al.
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. [...]

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. [...]

BSM Benchmarks for Effective Field Theories in Higgs and Electroweak Physics
/ Marzocca, David (INFN Trieste Italy) ; Riva, Francesco (Universite de Geneve (CH)) ; Criado, J (CAFPE Granada (Spain)) ; Dawson, S (BNL (US)) ; de Blas Mateo, Jorge (Universita e INFN, Padova (IT) and Durham University (UK)) ; Henning, Brian Quinn (CERN) ; Liu, D (Argonnne (US)) ; Low, I (Argonne (US)) ; Murphy, C (BNL (US)) ; Perez-Victoria Moreno De Barreda, Manuel Maria (Universidad de Granada (ES)) et al.
Effective Field Theories (EFTs) capture effects from heavy dynamics at low en- ergy and represent an essential ingredient in the context of Standard Model (SM) precision tests. This document gathers a number of relevant scenarios for heavy physics beyond the SM and presents explicit expressions for the Wilson coeffi- cients in their low-energy EFT. [...]

Diboson resonant production in non-custodial composite Higgs models
/ Carmona, Adrian (Zurich, ETH) ; Delgado, Antonio (Notre Dame U. ; CERN) ; Quirós, Mariano (Barcelona, IFAE ; ICREA, Barcelona) ; Santiago, Jose (CAFPE, Granada ; Granada U., Theor. Phys. Astrophys.)
We show that the recently reported excess in resonant diboson production can be explained in the context of non-custodial composite Higgs models. Dibosons are generated via the s-channel exchange of massive vector bosons present in these models. [...]

Observable Effects of General New Scalar Particles

We classify all possible new scalar particles that can have renormalizable linear couplings to Standard Model fields and therefore be singly produced at colliders. We show that this classification exhausts the list of heavy scalar particles that contribute at the tree level to the Standard Model effective Lagrangian to dimension six. [...]

Collider limits on leptophilic interactions
/ del Aguila, Francisco (CAFPE, Granada ; Granada U., Theor. Phys. Astrophys.) ; Chala, Mikael (CAFPE, Granada ; DESY) ; Santiago, Jose (CAFPE, Granada ; CERN) ; Yamamoto, Yasuhiro (CAFPE, Granada)
Leptophilic interactions can only be observed at the LHC in four-lepton final states. If these interactions are mediated by a resonance in the di-leptonic channel with renormalizable couplings, the mediator must have spin 1. [...]
