- 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 1,0 times more energy than what's produced in the most powerful colliders on Earth. Let's compare this event to an ordinary baseball with a mass of 146 g. Please use three significant figures in your calculations.9. Compare the electron, proton, and neutron a) in terms of mass, b) in terms of charge. c) Which of these particles are leptons and which are baryons. Application Questions 10. Use the table of Fundamental Particles and Interactions to answer the following a. What is the unified theory of the weak and electromagnetic interaction called? b. What particles experience the strong force? c. What particles mediate the weak interaction? Which of these is the most massive? 11.
