Physics - Particle Physics - Quarks, leptons, and hadrons - The Particle Classification

4 sections. Section 1 'Quarks': 6 flavors in 3 generations: (u,d), (c,s), (t,b). Properties: spin ½, fractional electric charge (+2/3 or -1/3), color charge (red/green/blue), baryon number 1/3. Antiquarks: opposite charge, anticolor, baryon number -1/3. Quarks interact via strong force (gluons), EM
