Q: 1. The following decays do not occur in the Standard Model. State why they do not occur, giving all…

A: (i) TK- decay involves the transformation of a kaon (a meson containing a strange quark) into a pion…

Q: Do all hadrons with a strange quark also have nonzero strangeness?

A: Quarks are treated as fundamental particles. There were three quarks initially, which accounted for…

Q: Give three (3) combinations of quarks (not antiquarks!) that will give baryons with the following…
