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 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.

Global Bayesian Analysis of the Higgs-boson Couplings
/ de Blas, Jorge (INFN, Rome) ; Ciuchini, Marco (INFN, Rome3) ; Franco, Enrico (INFN, Rome) ; Ghosh, Diptimoy (INFN, Rome) ; Mishima, Satoshi (Rome U. ; SISSA, Trieste) ; Pierini, Maurizio (CERN) ; Reina, Laura (Florida State U.) ; Silvestrini, Luca (INFN, Rome)
We present preliminary results of a bayesian fit to the Wilson coefficients of the Standard Model gauge invariant dimension-6 operators involving one or more Higgs fields, using data on electroweak precision observables and Higgs boson signal strengths..

New Physics in $b \to s \ell^+ \ell^-$ confronts new data on Lepton Universality
/ Ciuchini, Marco (INFN, Rome3) ; Coutinho, António M. (INFN, Rome3 ; Lisbon, CFTP) ; Fedele, Marco (ICC, Barcelona U.) ; Franco, Enrico (INFN, Rome) ; Paul, Ayan (DESY ; Humboldt U., Berlin) ; Silvestrini, Luca (INFN, Rome ; CERN) ; Valli, Mauro (UC, Irvine)
In light of the very recent updates on the $R_K$ and $R_{K^*}$ measurements from the LHCb and Belle collaborations, we systematically explore here imprints of New Physics in $b \to s \ell^+ \ell^- $ transitions using the language of effective field theories. We focus on effects that violate Lepton Flavour Universality both in the Weak Effective Theory and in the Standard Model Effective Field Theory. [...]

Hadronic uncertainties in the $B\to K^*\mu^+\mu^-$ decay
/ Ciuchini, Marco (INFN, Rome3) ; Coutinho, Antonio M. (INFN, Rome3 ; Rome III U.) ; Fedele, Marco (Orsay, LPT) ; Franco, Enrico (INFN, Rome) ; Paul, Ayan (DESY ; Humboldt U., Berlin) ; Silvestrini, Luca (CERN ; INFN, Rome) ; Valli, Mauro (UC, Irvine)
Motivated by the persisting 'anomaly' in the measurement of $P_5^\prime$, we review hadronic uncertainties entering the angular observables of the decay $\bar B\to {\bar K}^*\mu^+\mu^-$. We argue that hadronic uncertainties could account for the present measurements. [...]

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. [...]
