Beside neutrino masses, an assortment of precision observables probe new physics in the lepton sector. Experimental anomalies include a 3.5-sigma discrepancy in the anomalous magnetic moment of the muon and a 4-sigma indication of lepton universality violation in B-meson semi-leptonic decays. Effective field theory is a useful framework for studying observables sensitive to multi-TeV scales in...

In the near future, fundamental interactions at high-energy scales may be most efficiently studied via precision measurements at low energies. In this talk I will discuss the possible impact of the DUNE neutrino experiment on constraining the SM Effective Field Theory. The unprecedented neutrino flux offers an opportunity to greatly improve the current limits via precision measurements of the...

The understanding of flavor and the strong CP problem could be closely related. Motivated by the idea of Comprehensive Unification of elementary particle forces and families, we propose a minimal SO(3) flavor extension of the of the Standard Model which accounts for the observed fermion mass hierarchies, and provides a dynamical understanding of quark mixing and CP violation.

The models with the gauge group $SU(3)_c\times SU(3)_L\times U(1)_X$ (331-models) have
been advocated to explain why there are three fermion generations in Nature. As such they
provide partial understanding of the flavour sector. The hierarchy of fermion masses in
the Standard Model is another puzzle which remains without compelling explanation. In this
talk I present a model that incorporates...
