List of baryons
The following tables contain the ground states of all known and predicted baryons with total angular momentum J = 1 ⁄ 2 or J = 3 ⁄ 2 and positive parity .
The symbols used in the tables are:
- ( Isospin ), ( Total angular momentum ), ( Parity ), ( Electric charge ), ( Baryon number ), ( Strangeness ), ( Charm ), ( Bottomness ),
- u ( Up Quark ), d ( Down Quark ), s ( Strange Quark ), c ( Charm Quark ) and b ( Bottom Quark ) as well
- the symbols for the particles themselves: p, n and Greek capital letters .
The properties and the quark composition of the particles are listed in each case . For the corresponding antiparticles quarks are replaced by anti-quarks and the sign of the quantum numbers , , , and are reversed. Values in red are not yet confirmed with certainty by the experiment, but predicted by the Quark model and in agreement with the measurements.
The numbers in brackets after a numerical value indicate the uncertainty in the last digits of the value. (Example: The specification 1192.642 (24) has the same meaning as 1192.642 ± 0.024.)
nomenclature
Baryons are denoted by the symbols N , Δ , Λ , Σ , Ξ and Ω , which can also be provided with subscript lowercase letters c and b . The naming takes place according to the following rules:
- Baryons with 3 u or d quarks are called N ( isospin 1 ⁄ 2 ) or Δ (isospin 3 ⁄ 2 ).
- Baryons with 2 u or d quarks are called Λ (isospin 0) or Σ (isospin 1). If the third quark is a heavy quark ( c or b ), a corresponding subscript is appended.
- Baryons with 1 u- or d-quark are called Is (isospin 1 ⁄ 2 ). Remaining heavy quarks are again labeled with one or two subscripts, e.g. B. Ξ c , Ξ cc or Ξ b .
- Baryons with 0 u or d quarks are called Ω (isospin 0). Heavy quarks are identified by up to three subscriptions.
- In the case of baryons, which decay due to the strong interaction , the mass is placed in brackets.
- Each baryon can be assigned an antiparticle which is composed of the corresponding antiquarks. Antiparticles are marked with a dash: for example, stands for a proton , for an antiproton .
In summary, the number of u and d quarks and the isospin determine the symbol of the particle, and subscript lower case letters indicate heavy quarks.

Baryon resonances
The following table summarizes the names, quantum numbers (if known), and current status of the baryons. Baryon resonances are short-lived excitations from baryons; their mass is in brackets. For resonances of N, Δ and Ξ the partial waves of the πN-scattering are indicated with the symbol , where the orbital angular momentum is (S, P, D, F etc.). denotes the isospin and is the total angular momentum. For resonances of Λ and Σ, the K N partial wave is given accordingly . The spin parity (if known) is given for each particle.

Existence is certain, properties are at least somewhat known. |
Existence is almost certain to certain, but further confirmation is desirable and / or quantum numbers, branching ratios , etc. are not well determined. |
Evidence for the existence is only mediocre ( English fair ). |
Evidence for the existence of weak ( english poor ). |
