Semileptonic charged-current (CC) interactions are crucial for exploring the nuances of the Standard Model (SM) and its possible extensions. Recent examinations have underscored discrepancies with the SM predictions, particularly in the Cabibbo Angle Anomaly (CAA), which demonstrates a 3$\sigma$ deviation from zero. In this paper, we undertake a rigorous analysis using the SMEFT framework to...
Effective field theories offer a rationale for the classification of heavy new physics models based on the size of their contribution to the effective Lagrangian and therefore to experimental observables. When trying to connect theory with experiment, dictionaries which relate possible UV scenarios with the relevant effective interactions are of utmost importance.
In this talk, I will report...
TeV-scale new physics is generally very constrained by a plethora of measurements at different energy scales, ranging from flavour observables to the LHC's proton-proton collisions, with stronger bounds typically associated with fermions of the first two generations and with flavour-changing transitions.
It is therefore clear that any such low-scale new physics requires an organising...
Probing the Higgs potential through the measurement of the trilinear Higgs coupling is one of the main goals of particle physics. Large deviations from the Standard Model (SM) prediction can be accommodated in models with extended Higgs sectors while being in agreement with all existing experimental and theoretical constraints. In the framework of the Two Higgs Doublet Model, we study the...
