Neutrinos

Janet Conrad has a plan to catch the sterile neutrino — an elusive particle, possibly glimpsed by a number of experiments, that would upend what we know about the subatomic world.

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.
