$b$-physics

A Tale with Precision

The role of precision tests of the Standard Model is reviewed. Historically, they were key in establishing the theory and to verify its renormalizable structure, as well as the presence of radiative corrections. Today the emphasis has shifted to the …

Collider Phenomenology of Simple $Z^\prime$ Models for $b \to s \mu^+ \mu^-$ Anomalies

The $b \to s \mu^+ \mu^-$ anomalies constitute a set of measurements which collectively disagree with Standard Model predictions at high significance. We describe a simple anomaly free $Z^\prime$ model (the Third Family Hypercharge Model) and …

Search for new physics with rare B decays

Recently, several consistent deviations from the Standard Model predictions have been measured in flavour physics observables, and in particular in semileptonic B decays. In this presentation, I will discuss thier new physics implications within a …

B anomalies and the flavor of SMEFT

Recent data in B-meson decays indicate a coherent pattern of deviations from the Standard Model predictions. These 'anomalies' provide a perfect playground for using the Standard Model Effective Field Theory (SMEFT) in a bottom-up approach, not only …
