For three decades, a riddle has followed neutrinos, the near-weightless particles that stream through Earth by the trillions each second. They change identities as they fly, shifting among three known ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

The new measurement from the Muon g-2 experiment at Fermilab strongly agrees with the value found at Brookhaven and diverges from theory with the most precise measurement to date. The long-awaited ...

The deviant behavior of a subatomic particle might point to undiscovered forms of matter and energy in the universe. Or it might not. By Katrina Miller Katrina Miller reported on the last result from ...

Excavation workers have finished carving out the future home of the gigantic particle detectors for the international Deep Underground Neutrino Experiment. Located a mile below the surface of Lead, ...

The team working on Fermilab's Muon g−2 experiment has reported a tantalizing hint of a new type of physics. If confirmed, this would become the fifth fundamental force in the universe. Share on ...
