Advancing understanding of the subatomic matter of the universe

Subatomic Physics (P-25) conducts basic research in nuclear and particle physics, applying this expertise to solve problems of national importance.

We extend the limits of understanding of the smallest building blocks of matter with diverse experiments that explore subatomic reactions, providing a more thorough understanding of the constituents of our universe.

We employ nuclear physics techniques to study matter in the extreme and transient pressures produced by high explosives.

We are composed of people with a broad base of skills exploring both fundamental physics questions and practical applications of nuclear and particle physics.

Our group includes scientists, engineers, technologists and technicians, postdoctoral researchers, and graduate, undergraduate, high school student interns, and support personnel.

We are home to two active, one senior (retired), and four retired Los Alamos National Laboratory Fellows, and six American Physical Society Fellows.

Expertise

We lead or play a major role in large-scale collaborations with physicists from universities and institutions around the world, performing experiments at world-class facilities, including the following:

  • The search for the quark-gluon plasma at Brookhaven National Laboratory’s Relativistic Heavy Ion Collider
  • The quest for sterile neutrinos at Fermi National Accelerator Laboratory
  • The measurement of the neutron electron dipole moment, which will run at Oak Ridge National Laboratory’s Spallation Neutron Source
  • The study of neutron decay at the Laboratory’s Ultracold Neutron Source facility in order to examine the fundamental properties of matter, including a neutron lifetime experiment and the UCNA experiment studying the electron's momentum in polarized decay
  • Radiography of dynamic materials in real time using the Laboratory’s LANSCE accelerator
  • The use of naturally produced muons from cosmic rays to image the interior of structures and detect the smuggling of nuclear materials
  • Quark energy loss and proton spin structure studies at Fermi National Accelerator Laboratory
