Physics - Particle Physics - Quarks, leptons, and hadrons - Hadron Builder

Interactive tool to build hadrons from quarks. Left panel: quark palette (u, d, s, c, b and their antiquarks) with their properties (charge, mass, color). Right panel: building area. Students drag quarks to combine them. Rules enforced: (1) Baryons = exactly 3 quarks (one red, one green, one blue =
