Nuclear Physics

A roadmap of matter that will help unlock the secrets of how the universe is put together

Transforming our understanding of energy and matter to advance national, economic and energy security

The DOE Office of Science's Nuclear Physics (NP) program supports the experimental and theoretical research needed to create this roadmap. This quest requires a broad approach to different, but related, scientific frontiers:

  • Improving the understanding of the building blocks of matter
  • Discovering the origins of nuclei
  • Identifying the forces that transform matter

Stewardship of the field is shared with the National Science Foundation's (NSF's) Nuclear Physics Program. DOE and NSF fund almost all basic research in nuclear physics.

LANL nuclear physics

The Los Alamos Nuclear Physics portfolio includes:

  • Discovery and applied science thrust areas
  • Understanding quantum chromodynamics
  • Searching for new physics beyond the current Standard Model
  • Applications of nuclear physics to important national problems

LANL physics collaborations

Laboratory nuclear data and nuclear theory support the following collaborations:

  • Heavy ion and spin physics on the PHENIX Experiment at the Brookhaven Relativistic Heavy Ion Collider. 
  • Physics with cold and ultracold neutrons at the Oak Ridge Spallation Neutron Source Fundamental Neutron Physics Beam Line.
  • The MAJORANA DEMONSTRATOR Experiment at the Sanford Underground Research Facility in South Dakota, which will search for neutrinoless double-beta decay. 
  • Theory collaborations: SCIDAC, NUCLEI, TMD, DBD and FIRE.
  • Isotope Production & Applications
  • PHENIX Detector Collaboration at RHIC
  • Ultra-Cold Neutron Facility
