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.

Isospin-breaking corrections to the muon magnetic anomaly in Lattice QCD
/ Giusti, Davide (Rome III U. ; INFN, Rome3) ; Lubicz, Vittorio (Rome III U. ; INFN, Rome3) ; Martinelli, Guido (Rome U.) ; Sanfilippo, Francesco (INFN, Rome3) ; Simula, Silvano (INFN, Rome3)
In this contribution we present a lattice calculation of the leading-order electromagnetic and strong isospin-breaking (IB) corrections to the quark-connected hadronic-vacuum-polarization (HVP) contribution to the anomalous magnetic moment of the muon. The results are obtained adopting the RM123 approach in the quenched-QED approximation and using the QCD gauge configurations generated by the ETM Collaboration with $N_f = 2+1+1$ dynamical quarks, at three values of the lattice spacing ($a \simeq 0.062, 0.082, 0.089$ fm), at several lattice volumes and with pion masses between $\simeq 210$ and $\simeq 450$ MeV.

Non-perturbative renormalization in QCD+QED and its applications to weak decays
/ Di Carlo, Matteo (Rome U. ; INFN, Rome) ; Martinelli, Guido (Rome U. ; INFN, Rome) ; Giusti, Davide (Rome III U. ; INFM, Trieste) ; Lubicz, Vittorio (Rome III U. ; INFN, Rome3) ; Sachrajda, Christopher T. (Southampton U.) ; Sanfilippo, Francesco (INFN, Rome3) ; Simula, Silvano (INFN, Rome3) ; Tantalo, Nazario (Rome U., Tor Vergata ; INFN, Rome2)
We present a novel strategy to renormalize lattice operators in QCD+QED, including first order QED corrections to the non-perturbative evaluation of QCD renormalization constants. Our procedure takes systematically into account the mixed non-factorizable QCD+QED effects which were neglected in previous calculations, thus significantly reducing the systematic uncertainty on renormalization corrections.

Radiative corrections to semileptonic decay rates

We discuss the theoretical framework required for the computation of radiative corrections to semileptonic decay rates in lattice simulations, and in particular to those for $K_{\ell3}$ decays. This is an extension of the framework we have developed and successfully implemented for leptonic decays. [...]

HVP contribution of the light quarks to the muon $(g - 2)$ including isospin-breaking corrections with Twisted-Mass fermions
/ Giusti, Davide (Rome III U. ; INFN, Rome3) ; Lubicz, Vittorio (Rome III U. ; INFN, Rome3) ; Martinelli, Guido (Rome U. ; INFN, Rome) ; Sanfilippo, Francesco (INFN, Rome3) ; Simula, Silvano (INFN, Rome3) ; Tarantino, Cecilia (Rome III U. ; INFN, Rome3)
We present a preliminary lattice calculation of the leading-order electromagnetic and strong isospin-breaking corrections to the Hadronic Vacuum Polarization (HVP) contribution of the light quarks to the anomalous magnetic moment of the muon. The results are obtained in the quenched-$QED$ approximation using the $QCD$ gauge configurations generated by the European Twisted Mass Collaboration (ETMC) with $N_f = 2 + 1 + 1$ dynamical quarks, at three values of the lattice spacing varying from $0.089$ to $0.062 ~ \mbox{fm}$, at several lattice volumes and with pion masses in the range $M_\pi \simeq 220 \div 490 ~ \mbox{MeV}$..

Review of lattice results concerning low energy particle physics
/ Colangelo, Gilberto (Bern U.) ; Durr, Stephan (Wuppertal U. ; IAS, Julich) ; Juttner, Andreas (CERN) ; Lellouch, Laurent (Marseille, CPT) ; Leutwyler, Heinrich (Bern U.) ; Lubicz, Vittorio (Rome III U. ; INFN, Rome3) ; Necco, Silvia (CERN) ; Sachrajda, Christopher T. (Southampton U.) ; Simula, Silvano (INFN, Rome3) ; Vladikas, Anastassios (INFN, Rome2 ; Rome U., Tor Vergata) et al.
We review lattice results relevant for pion and kaon physics with the aim of making them easily accessible to the particle physics community. Specifically, we review the determination of the light-quark masses, the form factor f_+(0), relevant for the semileptonic K -> pi transition at zero momentum transfer as well as the ratio f_K/f_pi of decay constants and discuss the consequences for the elements V_{us} and V_{ud} of the CKM matrix.
