Are positrons classified as a lepton or a quark?

A positron is a lepton, because it is an anti-electron. An electron is a lepton, and a particle falls under the same classification as its antiparticle. This can also be shown to be true because a lepton is defined as a particle that does not experience the strong nuclear force, and positrons, like electrons, do not.
Correspondingly, only quarks have antiquarks as antiparticles.

Positrons are classified as a lepton, same as an electron. This is due to the fact that positrons, like electrons, do not act in the strong nuclear force. Only Quarks do this. That is the main distinction between the two types of fermions. Quarks react in the strong nuclear force, while leptons do not. Each have spin 1/2, however.
