matter-antimatter asymmetry

The first official evidence of a key imbalance between neutrinos and antineutrinos provides one of the best clues for why the universe contains something rather than nothing.

Three physicists stumbled across an unexpected relationship between some of the most ubiquitous objects in math.

Updated results from a Japanese neutrino experiment continue to reveal an inconsistency in the way that matter and antimatter behave.

A hint that neutrinos behave differently than antineutrinos suggests an answer to one the biggest questions in physics.

Physicists have completed a new round of searches for the answer to why matter dominates over antimatter. But the radioactive decay that would solve the puzzle is evading them.
