Question

Quizplus · Accepted Answer

Leptons are particles that do not interact via the strong force. Spin 1/2 particles such as electrons, neutrinos, and muons are examples of leptons. Baryons (ex. protons and neutrons) and mesons (ex. pions and kaons) are hadrons, which interact via the strong force. Intermediate (or gauge) bosons, such as W and Z bosons, mediate the weak force.
