Three quarks of different colors, giving a baryon with baryon number +1, Three antiquarks of different anticolors, giving an antibaryon with baryon number −1. The baryon number was defined long before the quark model was established, so rather than changing the definitions, particle physicists simply gave quarks one third the baryon number.
These lists detail all known and predicted baryons in total angular momentum J = 1 / 2 and J = 3 / 2 configurations with positive parity. [5]Baryons composed of one type of quark (uuu, ddd, ...) can exist in J = 3 / 2 configuration, but J = 1 / 2 is forbidden by the Pauli exclusion principle.
In particle physics, a baryon is a type of composite subatomic particle that contains an odd number of valence quarks, conventionally three. [1] Protons and neutrons are examples of baryons; because baryons are composed of quarks, they belong to the hadron family of particles. Baryons are also classified as fermions because they have half ...

Feynman diagram representing the decay of a lambda baryon Λ 0 b into a kaon K − and a pentaquark P + c. In July 2015, the LHCb collaboration at CERN identified pentaquarks in the Λ 0 b →J/ψK − p channel, which represents the decay of the bottom lambda baryon (Λ 0 b) into a J/ψ meson (J/ψ), a kaon (K −) and a proton (p).
The capture of a Ξ − baryon by a nucleus can make a Ξ − exotic atom or hypernucleus. [33] Upon capture, it changes to a ΛΛ hypernucleus or two Λ hypernuclei. [47] The disadvantage is that the Ξ − baryon is harder to make into a beam than singly strange hadrons. [48]
The symbols encountered in these lists are: I (), J (total angular momentum), P (), u (), d (), s (strange quark), c (charm quark), t (), b (bottom quark), Q ...
