FranA baryon is made up of three quarks. There are two types of baryons: protons, which consist of two up quarks and one down quark, and neutrons, which consist of one up quark and two down quarks. Quarks are elementary particles that are held together by the strong nuclear force to form protons and neutrons within the atomic nucleus.

Is a kaon a baryon?
No, a kaon is a meson, not a baryon. Baryons are particles composed of three quarks, while mesons are composed of a quark and an antiquark. Kaons contain a strange quark and an anti-up or anti-down quark.
Which combination of quarks can produce a neutral baryon?
A neutral baryon can be produced by combining three quarks that add up to neutral charge. For example, a proton consists of two up quarks and one down quark, while a neutron consists of one up quark and two down quarks.
What is a baryon acoustic oscillation?
Baryon acoustic oscillations are sound waves that traveled through the early universe, leaving behind a pattern of baryon (normal matter) density fluctuations. These fluctuations are observed in the distribution of galaxies and provide a standard ruler for measuring the expansion rate of the universe. Baryon acoustic oscillations are a key tool for studying the large-scale structure of the cosmos and probing the nature of dark energy.
What is an antibottom quark?
An antibottom quark (or b-bar quark) is the antiparticle of a bottom quark. It has the same mass as a bottom quark but opposite electric charge and other quantum numbers. When a bottom quark meets an antibottom quark, they can annihilate each other and produce energy.
What are neutral pions made of?
Neutral pions are composed of a quark-antiquark pair, specifically an up quark and an anti-up quark or a down quark and an anti-down quark. They are the lightest mesons and are unstable, decaying rapidly into two photons.
