Particles are classified into fundamental and composite categories. Fundamental particles, which are not composed of other particles, include fermions (quarks and leptons). Quarks combine to form composite particles called hadrons, which are subdivided into baryons (protons and neutrons) and mesons (pions and kaons). This is an introduction to A Level Particle Physics.
