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. [...]

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. [...]

Search for pair-produced vector-like leptons in final states with third-generation leptons and at least three b quark jets in proton-proton collisions at $\sqrt{s}$ = 13 TeV / CMS Collaboration
The first search is presented for vector-like leptons (VLLs) in the context of the "4321 model'', an ultraviolet-complete model with the potential to explain existing B physics measurements that are in tension with standard model predictions. The analyzed data, corresponding to an integrated luminosity of 96.5 fb$^{-1}$, were recorded in 2017 and 2018 with the CMS detector at the LHC in proton-proton collisions at $\sqrt{s} = $ 13 TeV.

Charm Physics Confronts High-$p_T$ Lepton Tails / Fuentes-Martin, Javier (Zurich U.) ; Greljo, Admir (CERN) ; Martin Camalich, Jorge (IAC, La Laguna ; Laguna U., Tenerife) ; Ruiz-Alvarez, José David (Antioquia U.)
We present a systematic survey of possible short-distance new-physics effects in (semi)leptonic charged- and neutral-current charmed meson decays. Using the Standard Model Effective Field Theory (SMEFT) to analyze the most relevant experimental data at low and high energies, we demonstrate a striking complementarity between charm decays and high invariant mass lepton tails at the LHC.

A UV-complete model for B anomalies and SM flavor hierarchies / Fuentes-Martín, Javier (Zurich U.)
In this talk I present a "flavor decontruction" of the Pati-Salam gauge groupas a possible description for the hints of lepton-flavor non-universality in $B$ decays. The model connects the observed pattern of " anomalies " to the origin of the Standard Model Yukawa couplings, while being consistent with low-and high-energy bounds. [...]

Maximal Flavour Violation: a Cabibbo mechanism for leptoquarks / Di Luzio, Luca (Durham U., IPPP) ; Fuentes-Martin, Javier (Zurich U.) ; Greljo, Admir (Mainz U., Inst. Phys. ; U. Mainz, PRISMA ; Sarajevo U.) ; Nardecchia, Marco (CERN ; INFN, Trieste) ; Renner, Sophie (Mainz U., Inst. Phys. ; U. Mainz, PRISMA)
We propose a mechanism that allows for sizeable flavour violation in quark-lepton currents, while suppressing flavour changing neutral currents in quark-quark and lepton-lepton sectors. The mechanism is applied to the recently proposed 4321 renormalizable model, which can accommodate the current experimental anomalies in $B$-meson decays, both in charged and neutral currents, while remaining consistent with all other indirect flavour and electroweak precision measurements and direct searches at high-$p_T$.

b → ss + − anomalies from dynamical Yukawas / Fuentes-Martin, Javier (Valencia U., IFIC)
The LHCb Collaboration has recently reported hints for New Physics in b → ss + − transitions that point to a large violation of flavor universality in the lepton sector. Motivated by them, we present a framework able to accommodate the experimental anomalies while, at the same time, addressing the flavor puzzle of the Standard Model. [...]

Gauge-invariant implications of the LHCb measurements on lepton-flavor nonuniversality / Celis, Alejandro (Munich U. ; Munich U., ASC) ; Fuentes-Martin, Javier (Valencia U., IFIC) ; Vicente, Avelino (Valencia U., IFIC) ; Virto, Javier (U. Bern, AEC)
We study the implications of the recent measurements of $R_K$ and $R_{K^*}$ by the LHCb collaboration. We do that by adopting a model-independent approach based on the Standard Model Effective Field Theory (SMEFT), in which the dominant new physics effects are encoded in the coefficients of dimension-six operators respecting the full Standard Model (SM) gauge symmetry.
