Neutrinos

The KATRIN experiment is closing in on the mass of the neutrino, which could point to new laws of particle physics and shape theories of cosmology.

High-energy neutrinos have been traced back to a flaring supermassive black hole known as a blazar. The long-sought link opens the door to an entirely new way to study the universe.

An experiment at the Fermi National Accelerator Laboratory near Chicago has detected far more electron neutrinos than predicted — a possible harbinger of a revolutionary new elementary particle called the sterile neutrino, though many physicists remain skeptical.

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

The physicist and curios collector hopes to reveal the hidden structure lurking in the subatomic world.

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.
