Participate in the residual strong force
- Baryons participate in the residual strong force, which is mediated by particles known as mesons. The most familiar baryons are protons and neutrons, both of which contain three quarks, and for this reason they are sometimes called triquarks.

What is a meson & a baryon?
In particle physics, a baryon is a type of composite subatomic particle, including the proton and the neutron, that contains an odd number of valence quarks, conventionally three. Baryons belong to the hadron family of particles; hadrons are composed of quarks. Baryons are also classified as fermions because they have half-integer spin.
baryon, any member of one of two classes of hadrons (particles built from quarks and thus experiencing the strong nuclear force). Baryons are heavy subatomic particles that are made up of three quarks. Both protons and neutrons, as well as other particles, are baryons.

Baryons. Baryons are massive particles which are made up of three quarks in the standard model. This class of particles includes the proton and neutron. Other baryons are the lambda, sigma, xi, and omega particles. Baryons are distinct from mesons in that mesons are composed of only two quarks.
Baryon number is a generalization of nucleon number, which is conserved in non-relativistic nuclear reactions and decays. The law of conservation of baryon number states that: The sum of the baryon number of all incoming particles is the same as the sum of the baryon numbers of all particles resulting from the reaction.
The centerpiece is the set of eighteen baryons: particles, like the proton and neutron, composed of three lightweight quarks. This Insight provides an introduction to these baryons, whose discovery and classification constitute perhaps the first great achievement of what is now known as the standard model of particle physics.
Aug 1, 2017 · Articles. What is a Baryon? A baryon is a composite subatomic particle. It is made up of three quarks. The most stable baryons are protons and neutrons, so most building blocks of matter are baryons. Baryon comes from the Greek word βαρύς (barys) for heavy.
