Neutrinos may be nearly invisible, but they play a starring role in the Universe. Long-standing anomalies had hinted at a ...

This discovery is important because it ruled out a major possibility for new physics beyond the Standard Model.

After a decade of painstaking measurements, scientists have delivered a major plot twist in particle physics: a ...

High-precision measurements from the KATRIN experiment strongly limit the existence of light sterile neutrinos and narrow the search for new physics. Neutrinos are extremely difficult to detect, yet ...

Physicists are closing in on one of the most persistent mysteries in particle physics: whether a hidden kind of neutrino is ...

An extensive search for a hypothetical particle has turned up empty. The sterile neutrino is a proposed subatomic particle that could even be a candidate for the mysterious dark matter, and although ...

If an additional sterile neutrino existed, it would occasionally be emitted in the decay, producing a distinct distortion, or "kink," in the electron energy spectrum. KATRIN, located at the Karlsruhe ...

Particle physicists have gone to great lengths — including rowing onto the dark waters of a swimming pool-sized water tank and setting up a base in the Antarctic — to understand one of the universe’s ...

For decades, physicists have suspected an interloper. A reclusive, hypothetical subatomic particle might be creeping into studies of neutrinos, nearly massless particles with no electric charge. A new ...

William & Mary physicist Mike Kordosky is a skeptic on the sterile-neutrino question, but he says he would be happy to be proven wrong. He was instrumental in the design of an experiment that was ...

An observatory buried deep in Antarctic ice has reported the results of its search for an hypothesized particle called the ‘sterile neutrino’: a total blank. The null result, reported on 8 August in ...

Neutrinos are jerks. Think you understand particle physics? Neutrinos transmute from one form into one another thanks to their inexplicable mass. Think you know the difference between matter and ...
