• A neutral K meson (mass 497.7 MeV/c2 ) is moving with a kinetic energy of 77.0 MeV. It decays into a pi meson (mass 139.6 MeV/c2 ) and another particle of unknown mass. The pi meson is moving in the direction of the original K meson with a momentum of 381.6 MeV/c. i. Find the momentum and total relativistic energy of the unknown particle. ii. By finding the mass of the unknown particle show that the unknown particle is...

What theoretical explanations exist for the fact that there are three generations of leptons and quarks?...

What theoretical explanations exist for the fact that there are three generations of leptons and quarks? I'm not so much asking why there are exactly 3 generations, but rather what makes electron, muon and tau differ. Also, since the three families of quarks don't have to be a priori related to the three families of leptons, I'm interested in answers for either quarks, leptons, or both.
