International experiments build on Los Alamos expertise

Physics Division scientists and engineers investigate the field of high energy physics through experiments that strengthen our fundamental understanding of matter, energy, space, and time and play a significant role in two of the three high energy physics frontiers as defined by the Department of Energy’s Office of High Energy Physics.

Exploring intensity frontier

On the trail of one of the greatest mysteries in physics, researchers on the Long-Baseline Neutrino Experiment (LBNE) seek to discover why there is more matter than antimatter in the universe.

Through an international partnership, LBNE will use the most intense neutrino beam ever created and one of the largest neutrino detectors ever built to try to explain this asymmetry.

Exploring cosmic frontier

Los Alamos has a long history of neutrino research, from the Nobel-prize winning 1950s Cowan-Reines experiment that confirmed the existence of the antineutrino to modern experiments using large water Cherenkov detectors.

The High-Altitude Water Cherenkov (HAWC) telescope seeks to help solve the mystery of cosmic-ray origin.

Surveying the sky with 300 Cherenkov detectors arrayed on the slopes of Mexico’s Pico de Orizaba volcano, HAWC builds on the experience of Milagro, a detector experiment in the Jemez Mountains near Los Alamos that discovered new sources of gamma rays.
