Unlocking the Mass of Neutrinos

Neutrinos are the second most abundant particles in the Universe and have consequently played a key role in its evolution. Neutrino oscillation experiments show that they have very small, yet non-zero, mass rendering the Standard Model of particles incomplete. Therefore, neutrinos through their mass not only help us understand the universe at large scales but also provide compelling avenues for the exploration of physics beyond the Standard Model. In this talk, I will discuss two ongoing efforts to decipher the absolute scale and the nature of the neutrino mass: Project 8 direct neutrino mass measurement experiment and CUORE/CUPID neutrinoless double beta decay experiments. I will present the Project 8 experiment’s first limit on neutrino mass employing cyclotron radiation emission spectroscopy and the ongoing research and development for the future phases. I will also present the latest results from the CUORE experiment’s search for neutrinoless double beta decay and plans for the upcoming CUPID experiment to extend the sensitivity. I will further discuss the complementarity of these efforts and the prospects of pushing past the inverted neutrino mass ordering.
