Title
Flavor Anomalies and New Physics Exploration
Speaker
Prof. Fanrong Xu (Jinan University, China)Abstract
Anomalies in b -> s l l and b -> c l nu decays have persisted for over a decade. In this talk, I will explore the current landscape from three perspectives. First, global fits offer a model-independent approach to understanding the latest data. I will present our recent work on global fits incorporating around 200 binned observables, which reveals intriguing indications that new physics may manifest in the Wilson coefficient C9. Second, the Standard Model Effective Field Theory (SMEFT) provides a less model-dependent interpretation of experimental data and fitting outcomes. I will highlight several compelling predictions that emerge when data is analyzed through the SMEFT framework. Finally, the exploration and testing of specific new physics models remain crucial. I will introduce and examine a specific Two-Higgs-Doublet Model (2HDM) with gauge symmetry imposed on fermions, known as the Flavor Gauged 2HDM, which accommodates anomalies in both neutral and charged currents.
