Neutrino Physics Through Atomic Reactions

Tsung-Dao Lee Institure

Neutrino physics is an exciting field of research. It contains many open questions that should point out to physics beyond the standard model. The neutrino mass model is unknown. The mass scale and the neutrino mixing matrix is not fully measured. The very nature of the neutrino, Dirac or Majorana, remains a mystery. The state of art in neutrino experiments uses long baseline oscillation and can only probe the mixing parameters. In this talk, I will discuss a novel idea to use atomic transitions with neutrino pair emission to probe neutrino mass scale and beyond standard model physics. The O(eV) energy scale of atomic transitions is perfect for investigating the existence and properties of neutrino mass and light mediators, and can provide complementary measurements to oscillation experiments in a very different energy scale.
