Baryon decuplet: Spin=3/2

Baryon octet: Spin=1/2

This is a list of baryons. See also quark model.

Note that all have baryon number +1. Antiparticles (not listed) have all quarks changed to antiquarks, and their baryon number, strangeness, charm, and bottomness quantum numbers have their signs flipped.
