Parallel Session Talk

The Standard Model Effective Field Theory (SMEFT) is an essential tool for probing physics beyond the Standard Model. With New Physics signals remaining elusive, deriving constraints on SMEFT Wilson coefficients is increasingly important in order to pinpoint its low-energy effects. This talk presents comprehensive global fits of SMEFT under the Minimal Flavour Violation (MFV) hypothesis. We...

Parallel Session Talk

Standard Model effective field theory (SMEFT) serves as a powerful and rigorous framework for systematically characterizing deviations from the Standard Model. However, due to its model-independent nature, there is an inevitable trade-off resulting in a significant increase in the number of independent parameters. In this talk, we discuss the charting of the SMEFT parameter space by...

16. Unifying Quark and Lepton Flavor Observables through Modular Symmetry

Parallel Session Talk

In this talk, I will present a novel unified analysis of quark and lepton flavor observables within the framework of modular symmetry, focusing specifically on a model based on 2O modular symmetry. Using a single complex modulus \tau and a well-defined set of real parameters, this model provides a comprehensive description of both quark and lepton sectors under a unified theoretical...

Parallel Session Talk

We discuss a three-Higgs-doublet model with an underlying $S_3$ symmetry, allowing in principle for complex couplings. In this framework it is possible to have either spontaneous or explicit CP violation in the scalar sector, depending on the regions of parameter space corresponding to the different possible vacua of the $S_3$ symmetric potential. We list all possible vacuum structures...
