- n. Any of a family of subatomic particles, including the nucleon and hyperon multiplets, that participate in strong interactions, are composed of three quarks, and are generally more massive than mesons. Also called heavy particle. See Table at subatomic particle.
- n. physics A heavy subatomic particle created by the binding of quarks by gluons; a hadron containing three quarks. Baryons have half-odd integral spin and are thus fermions. This category includes the common proton and neutron of the atomic nucleus.

- 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.

- Greek barus, heavy; see gwerə-1 in Indo-European roots + -on1. (American Heritage® Dictionary of the English Language, Fourth Edition)
“This pattern is known by the term "baryon acoustic oscillations".”
“Since 1970, theorists had been predicting another, subtler structure, superimposed on the 300-million-light-year structure and called baryon acoustic oscillations.”
“A baryon is a particle of matter made of three fundamental building blocks called quarks.”
“BOSS, the Baryon Oscillation Spectroscopic Survey, is the most ambitious attempt yet to history of the Universe using the technique known as baryon acoustic oscillation (BAO).”
“For that purpose the scientists developed a device called a baryon reverter that’s supposed to seal the breach between universes or limit its size, I’m not sure which.”
“At the beginning of the project, no one had known the universe was accelerating, no one had heard of dark energy, and baryon acoustic oscillations lived in the small details of theory; certainly no one had measured them.”
“In the second place, the baryon ripples are shallow and show up only statistically, only in the math.”
“Iâ€ ™ ve adjusted my sensors to detect baryon waves.”
“The conversion of a quark to the strange quark in a baryon transitions a neutron to a lower energy state, and similarly a proton with a weak process in addition.”
“A baryon or proton is a region with a confined QCD vacuum that has considerable amounts of energy.”
