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 ), ( Bottom Ness ), u (up- quark ), d ( down quark ), s ( strange quark ), c ( charm quark ) and b ( bottom quark ) and the symbols for the particles themselves

The numbers in parentheses following a numerical value represent the uncertainty in the last digits of the value. (Example: Specifying 1115.683 (6 ) is equivalent to 1115.683 ± 0.006. )


Baryons are denoted by the symbols N, Δ, Λ, Σ, Ξ and Ω, which can be provided with subscript lowercase additionally. The appointment is subject to the following rules:

In summary determine the number of u and d quarks and isospin of the symbol of the particle, and subscript lowercase letters show heavy quarks.

The following table summarizes the names, the quantum numbers ( if known ) together and the current status of the baryons. Baryon resonances are short-lived excitations of baryons; its mass is in brackets. For resonances of N, Δ and Ξ the partial waves of πN scattering are indicated by the symbol, the orbital angular momentum (S, P, D, F, etc.). denotes the isospin and the total angular momentum. For resonances of Λ and Σ the CN - partial wave is correspondingly given.
