The video tutorial provides a comprehensive overview of particle classification, focusing on hadrons and leptons. Leptons are fundamental particles interacting through weak and electromagnetic forces, with six types and corresponding anti-leptons. Hadrons, composed of quarks, are non-fundamental and interact via strong forces. Baryons, a subgroup of hadrons, include protons and neutrons, with specific quark compositions and baryon numbers. Mesons, another hadron subgroup, consist of quark-antiquark pairs and exhibit strangeness, a property conserved in strong interactions.
