The Facility for Rare Isotope Beams will help scientists unlock the inner workings of atomic nuclei and explore how elements formed in the cosmos.
A lunar particle collider that dwarfs any such facility on Earth might not be impossible, according to new calculations.
Despite the LHC’s fame, all its detectors were oblivious to neutrinos. But not anymore.
At 0.28 trillionths of a millimeter thick, the shell of neutrons around the nucleus of an atom of lead is a bit thicker than physicists had predicted.
At less than an electron volt, neutrinos are by far the most lightweight massive particles known, a new measurement confirms.
In the last century, physicists learned to split atomic nuclei and revealed a complex world of fundamental particles.
After two decades, a new measurement of the muon magnetic anomaly reinforces earlier hints that its value disagrees with standard physics.
Physicists have finally used laser cooling to tame unruly antimatter atoms. That could allow new tests of symmetry and Einstein’s theory of gravity.
The SeaQuest experiment finds that down antiquarks within the proton are more prevalent than up antiquarks.
In the 1970s, physicists confirmed particles called quarks existed. Fifty years later, many kinds of quarks in many combinations have been discovered.
