According to the article Alien Antimatter Crashes into Earth e: More than 60 years ago, future Nobel laureate Sheldon Glashow predicted that if an antineutrino - the antimatter answer to the nearly massless neutrino - collided with electron, it could produce a cascade of other particles. The "Glashow resonance phenomenon is hard to detect, in large part because the antineutrino needs about 1, %3D times more energy than what's produced in the most powerful colliders on Earth.
