/ 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. [...]

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.

Electroweak precision observables and Higgs-boson signal strengths in the Standard Model and beyond: present and future
/ de Blas, Jorge (INFN, Rome) ; Ciuchini, Marco (INFN, Rome3) ; Franco, Enrico (INFN, Rome) ; Mishima, Satoshi (KEK, Tsukuba) ; Pierini, Maurizio (CERN) ; Reina, Laura (Florida State U. ; Santa Barbara, KITP) ; Silvestrini, Luca (INFN, Rome)
We present results from a state-of-the-art fit of electroweak precision observables and Higgs-boson signal-strength measurements performed using 7 and 8 TeV data from the Large Hadron Collider. Based on the HEPfit package, our study updates the traditional fit of electroweak precision observables and extends it to include Higgs-boson measurements. [...]

$\texttt{HEPfit}$: a Code for the Combination of Indirect and Direct Constraints on High Energy Physics Models
/ De Blas, J. (Padua U. ; INFN, Padua) ; Chowdhury, D. (Ecole Polytechnique, CPHT ; Orsay, LPT) ; Ciuchini, M. (INFN, Rome) ; Coutinho, A.M. (PSI, Villigen) ; Eberhardt, O.

$\texttt{HEPfit}$ is a flexible open-source tool which, given the Standard Model or any of its extensions, allows to $\textit{i)}$ fit the model parameters to a given set of experimental observables; $\textit{ii)}$ obtain predictions for observables. $\texttt{HEPfit}$ can be used either in Monte Carlo mode, to perform a Bayesian Markov Chain Monte Carlo analysis of a given model, or as a library, to obtain predictions of observables for a given point in the parameter space of the model, allowing $\texttt{HEPfit}$ to be used in any statistical framework.

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.

This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the search for Beyond the Standard Model (BSM) physics, of the High Luminosity (HL) phase of the LHC, defined as $3$ ab$^{-1}$ of data taken at a centre-of-mass energy of 14 TeV, and of a possible future upgrade, the High Energy (HE) LHC, defined as $15$ ab$^{-1}$ of data at a centre-of-mass energy of 27 TeV.
