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 an 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 1,000 times more energy than what's produced in the most powerful colliders on Earth.
1. What is the threshold antineutrino energy for the Glashow resonance in peta electronvolts (PeV)?
2. What is this threshold energy in units of joules?
3.Now consider a baseball with the same kinetic energy as that of the Glashow resonance. What speed in m/s would correspond to this energy?
4.What is this rate in units of inches/second?
If all of the quarks combining to form a meson are in the ground state, what are the possible spins a
meson might have? Give an example particle (and describe its constituents) for each of your answers.
Large quantities of antimatter isolated from normal matter should behave exactly like normal matter. An antiatom, for example, composed of positrons, antiprotons, and antineutrons should have the same atomic spectrum as its matter counterpart. Would you be able to tell it is antimatter by its emission of antiphotons? Explain briefly.
