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.
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?
For this problem, you may use your notes and the tables provided only.
a. For the given quark combination (s,s,d) determine the baryon number, the strangeness, and the electric charge quantum number, Q’. Recall, a particle’s charge q is related to its electric charge quantum number Q’ by q = eQ’. You may use the tables provided only.
b. Using the tables provided, identify the hadron that corresponds to the above data. Estimate the expected mass of the hadron.
c. Determine the hypercharge, the z-component of the isospin, and the isospin for the hadron given in your answer to part b) above
d. If the normal decay mode of this particle is the one given below, identify which one of the four fundamental interactions is most likely responsible for the equation listed below. Justify your answer.
