Neutrino

The next generation of neutrinoless double beta (0νββ) decay experiments and direct detection of dark matter require ultrapure detectors. The University of South Dakota is leading the development of ultra-pure germanium crystals. The project includes purification work through zo…

We explore physics Beyond the Standard Model in the dark matter and in the neutrino sectors. In both cases, we parametrize New Physics effects at low energy experiments with an Effective Field Theory (EFT) approach. We then propose a dynamical solution of the fermion mass hierar…

The lives of high-mass stars end with core-collapse supernovae, which distribute energy and chemical elements into the interstellar medium. This process is integral to the Galactic ecosystem, since stars and planets will form from the enriched interstellar medium. Since most sup…
