Nuclear physics at SLAC

The Weak Interactions in Nuclei (WIN) group uses the nucleus as a laboratory to study nature's fundamental interactions and symmetries. We work on experiments that test theories of exotic new physics and explore open questions in particle physics and cosmology. 

WINLab

Our work focuses on studying neutrinos: exploring the origin of their mass and their possible couplings to new particles or new physics. At present we are working on two fronts: 

  1. Testing the hypothesis that neutrinos are Majorana fermions via searches for neutrinoless double beta decay, and
  2. Searching for new particles that couple to neutrinos via precision measurements of weak nuclear decays using cryogenic/quantum detectors. 

Our efforts span data analysis from existing experiments as well as R&D into new detector technologies for next-generation searches. We work closely with the Noble Liquid Dark Matter and DMQIS groups at SLAC, as well as collaborators all over the world.
