neutrino

Physicists are using one of the oldest laws of nature to find the mass of the elusive neutrino.

The future of Fermilab is global, as exemplified by the DUNE international effort.

The United States and the European physics laboratory have formally agreed to partner on continued LHC research, upcoming neutrino research and a future collider.

Scientists don’t yet know what dark matter is made of, but they are full of ideas.

Matter and antimatter behave differently. Scientists hope that investigating how might someday explain why we exist.

The MicroBooNE collaboration announced that it has seen its first neutrinos in the experiment’s newly built detector.

Deep in the dense core of a black hole, protons and electrons are squeezed together to form neutrons, sending ghostly particles called neutrinos streaming out. Matter falls inward. In the textbook case, matter rebounds and erupts, leaving a neutron star. But sometimes, the supernova fails, and there’s no explosion; instead, a black hole is born. Scientists hope to use neutrino experiments to watch a black hole form.

Ghostlike subatomic particles called neutrinos could hold clues to some of the greatest scientific questions about our universe: What extragalactic events create ultra-high-energy cosmic rays? What happened in the first seconds following the big bang? What is dark matter made of?

Finding a small discrepancy in measurements of the properties of neutrinos could show us how they fit into the bigger picture. One of those properties is a parameter called theta13. Theta13 relates deeply to how neutrinos mix together, and it’s here that scientists have seen the faintest hint of disagreement from different experiments.

Experiments at Fermilab and other laboratories are investigating neutrino oscillations in detail to discover the physics beyond the Standard Model.
