Exploring fundamental symmetries through elusive neutrinos

by Dr Zoya Vallari (Caltech)

Description

Once an unlikely hypothesis not foreseen by the Standard Model, the existence of non-zero neutrino mass is now a well-accepted, experimentally verified fact. The extraordinary smallness of the neutrino mass and the weakness of neutrino interactions determine the scale of observable phenomena, making neutrino experiments acutely challenging. Neutrino oscillation experiments remain the first and solitary evidence of this scientific breakthrough, conclusively proving the existence of non-zero neutrino masses by the end of the 20th century.

 In this talk, I will outline how neutrino oscillation experiments continue to provide a rich environment to explore fundamental physics, specifically for determining the neutrino mass ordering and the potential discovery of charge-parity (CP) violation in the lepton sector.

I will review the current landscape of the results from the long-baseline neutrino oscillation experiments, and present the results from the new combined analysis of the data from the NOvA and the T2K experiments. Additionally, I will highlight how the upcoming next-generation experiments are being designed to enhance the precision of these measurements to meet the target sensitivities needed to achieve these ambitious physics goals.
