On December 6, 2016, a high-energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts (PeV) of energy. Deep inside ...

In a particle collider at CERN, a rarely-seen event is bringing us tantalizingly close to the brink of new physics. From years of running what is known as the NA62 experiment, particle physicist ...

Neutrinos and antineutrinos are elementary particles with small but unknown mass. High-precision atomic mass measurements have revealed that beta decay of the silver-110 isomer has a strong potential ...

A tank of the purest water, buried under kilometers of rock in Ontario, Canada, flashed as a barely detectable particle slammed through its molecules. This event was the first time that water had been ...

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