With the discovery of hundreds of subatomic particles, a huge diversity of particle interactions was seen. It became important to understand the underlying rules that govern elementary particle interactions. In this video I discuss few of those.
Lepton number can be assigned to each family of Leptons. The Electron Lepton number, Muon Lepton number, and Tau Lepton number are seen to be conserved whenever particle interactions involve lepton particles occur.
Baryon number is similarly assigned to baryon particles. Baryon and mesons belong to Hadrons. While mesons are made up of quark-antiquark pair and have a Baryon number of 0, the Baryons are made up of three quarks and have a Baryon number of 1. Baryon number is conserved on particle interactions involving such particles, Baryons (nucleons, hyperons etc)
Strangeness number is assigned to strange particles, which are named as such due to their strange behavior, i.e they are produced via Strong or EM interaction, but they decay va Weak interaction. They contain either one or more strange quark. Such strangeness number is assigned a value of -1 for each strange quark. The strangeness number is conserved for Strong and EM interactions but not for Weak interactions.
