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.

On hadronic uncertainties polluting the New Physics hunt in $b \rightarrow s$ transitions
/ 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 (INFN, Rome ; CERN) ; Valli, Mauro (UC, Irvine)
We review the hadronic uncertainties involved in the decay $B \rightarrow K^* \ell^+ \ell^-$, arguing that the non-factorizable hadronic contribution might account for some of the anomalies observed in $b \rightarrow s$ transitions, namely the ones relating to the $P^′_5$ observable. Moreover, we explore how alternative Beyond Standard Model interpretations of the anomalies pattern, e.g. [...]

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

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. [...]

The Global Electroweak and Higgs Fits in the LHC era

We update the global fit to electroweak precision observables, including the effect of the latest measurements at hadron colliders of the $W$ and top-quark masses and the effective leptonic weak mixing angle. We comment on the impact of these measurements in terms of constraints on new physics. [...]
