Zusammenfassung: | We present here the update of the Unitarity Triangle (UT) analysis performed
by the UTfit Collaboration within the Standard Model (SM) and beyond.
Continuously updated flavour results contribute to improving the precision of
several constraints and through the global fit of the CKM parameters and the SM
predictions. We also extend the UT analysis to investigate new physics (NP)
effects on $\Delta F=2$ processes. Finally, based on the NP constraints, we
derive upper bounds on the coefficients of the most general $\Delta F=2$
effective Hamiltonian. These upper bounds can be translated into lower bounds
on the scale of NP that contributes to these low-energy effective interactions. |
