Fermi National Accelerator Laboratory advances the understanding
of the fundamental nature of matter and energy by providing leadership
and resources for qualified researchers to conduct basic research
at the frontiers of high energy physics and related disciplines.
Almost every particle has an antimatter counterpart: a particle with the same mass but opposite charge, among other qualities. But certain characteristics of neutrinos and antineutrinos make scientists wonder: Are they one and the same? Are neutrinos their own antiparticles?
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
