Abstract
Flavour physics represents a unique test bench for the Standard Model (SM).
New analyses performed at the LHC experiments are now providing unprecedented
insights into CKM metrology and new evidences for rare decays. The CKM picture
can provide very precise SM predictions through global analyses. We present
here the results of the latest global SM analysis performed by the UTfit
collaboration including all the most updated inputs from experiments, lattice
QCD and phenomenological calculations. In addition, the Unitarity Triangle (UT)
analysis can be used to constrain the parameter space in possible new physics
(NP) scenarios. We update here also the UT analysis beyond the SM by the UTfit
collaboration. All of the available experimental and theoretical information on
\$\Delta F=2\$ processes is reinterpreted including a model-independent NP
parametrisation. We determine the allowed NP contributions in the kaon, \$D\$,
\$B\_d\$, and \$B\_s\$ sectors and, in various NP scenarios, we translate them into
bounds for the NP scale as a function of NP couplings.
