Hadrons and Leptons

• Leptons - Not affected by the strong force
• Hadrons - Affected by the strong force
  • Baryons
  • Mesons

Hadrons

Strongly interacting. Divided into baryons and mesons.

Baryons are fermions (incl. proton, neutron), their decay always produces another baryon, and ultimately a proton.

Mesons are bosons. Mesons can decay without producing other hadrons.

thought:: decay is another word for fields popping free from the others, no longer interacting, producing excitations that ar dis-entangled, ultimately producing single fundamental particles, i.e. excitations in their respective fields, not interacting (not bound up into more complex particles) ![[thought-decay is another word for fields popping free from the others.png]]
