Precision studies of the Cabibbo-Kobayashi-Maskawa matrix offer a very important testbed of the Standard Model (SM).In light of new inputs and measurements, in this proceeding we review the status of the Unitarity Triangle as a fundamental tool to uncover New Physics. We report the results of the latest SM global fits performed by the UTfit Collaboration including all the up-to-date experimental and theoretical inputs as for the Summer 2023 release.We also update the stringent constraints on New Physics from the generalized $|\Delta F| = 2$ effective Hamiltonian.

We present an updated global analysis of beauty decays sensitive to the angle $\gamma$ of the Cabibbo-Kobayashi-Maskawa matrix and of $D$-meson mixing data in the framework of approximate universality for charm mixing. [...]

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. [...]

Impact of the Recent Measurements of the Top-Quark and <math display="inline"><mi>W</mi></math>-Boson Masses on Electroweak Precision Fits
/ de Blas, J. (CAFPE, Granada ; Granada U.) ; Pierini, M. (CERN) ; Reina, L. (Florida State U.) ; Silvestrini, L. (INFN, Rome)
We assess the impact of the very recent measurement of the top-quark mass by the CMS Collaboration on the fit of electroweak data in the Standard Model and beyond, with particular emphasis on the prediction for the mass of the W boson. We then compare this prediction with the average of the corresponding experimental measurements including the new measurement by the CDF Collaboration, and discuss its compatibility in the Standard Model, in new physics models with oblique corrections, and in the dimension-six Standard Model Effective Field Theory.

Global analysis of electroweak data in the Standard Model
/ de Blas, J. (CAFPE, Granada ; Granada U.) ; Ciuchini, M. (INFN, Rome3) ; Franco, E. (INFN, Rome) ; Goncalves, A. (Florida State U.) ; Mishima, S. (KEK, Tsukuba) ; Pierini, M. (CERN) ; Reina, L. (Florida State U.) ; Silvestrini, L. (INFN, Rome)
We perform a global fit of electroweak data within the Standard Model, using state-of-the art experimental and theoretical results, including a determination of the electromagnetic coupling at the electroweak scale based on recent lattice calculations. In addition to the posteriors for all parameters and observables obtained from the global fit, we present indirect determinations for all parameters and predictions for all observables. [...]

The statistical models used to derive the results of experimental analyses are of incredible scientific value and are essential information for analysis preservation and reuse. In this paper, we make the scientific case for systematically publishing the full statistical models and discuss the technical developments that make this practical. [...]
