Scientists have inched a step closer to solving an enduring mystery in physics — why the universe contains any matter at all — thanks to a newly combined analysis from two of the world's leading ...

Our existence rests on a razor‑thin imbalance in the early cosmos. When the universe was young, matter and antimatter should ...

But only in the last 70 years have we known for certain they were there. In 1956, physicists Clyde Cowan and Frederick Reines ...

AMES, Iowa – Mayly Sanchez clicked to a presentation slide showing the telltale track of an electron neutrino racing through the 14,000-ton Far Detector of the NOvA Neutrino Experiment. Since that ...

Physicists have been chasing one of the universe’s strangest mysteries—neutrinos, nearly invisible particles that zip through everything, including you, billions of times every second. For the first ...

The joint NOvA-T2K analysis achieved unprecedented precision in measuring neutrino mass, a key step toward understanding ...

Scientists at Fermilab’s MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle ...

Where did all the matter in the universe come from? This is one of the biggest mysteries in fundamental physics, and exciting results released from the international T2K neutrino experiment in Japan ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

Experiments, however, have shown that neutrinos “ oscillate ” as they travel, switching among three different identities — physicists call them “flavors”: electron neutrino, muon neutrino and tau ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...
