Elementary particles with a baryon number = 1, this means: neutrons, protons, hyperons. The name (barys, Greek for "heavy") is derived from the relatively large mass of these particl [..]

  A three quark hadron.  The most common baryons are protons and neutrons.

A subatomic particle with a large rest mass, e.g., the proton.

A hadron made from three quarks. The proton (uud) and the neutron (udd) are both baryons. They may also contain additional quark-antiquark pairs.

a hadron consisting of three quarks

(particles) A heavy subatomic particle created by the binding of quarks by gluons. Baryons have half-odd integral spin and are thus fermions. This category includes the common proton and neutron of th [..]

(n) any of the elementary particles having a mass equal to or greater than that of a proton and that participate in strong interactions; a hadron with a baryon number of +1

A sub-class of hadrons. They are heavier particles which experience the strong nuclear force and include the proton and neutron. They are composed of triplets of quarks (Baggott).

is a proton, neutron, or any elementary particle that decays into a set of particles that includes a proton.
