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:

• ${\displaystyle I}$( Isospin ), ( Total angular momentum ), ( Parity ), ( Electric charge ), ( Baryon number ), ( Strangeness ), ( Charm ), ( Bottomness ), ${\displaystyle J}$ ${\displaystyle P}$ ${\displaystyle Q}$ ${\displaystyle B}$ ${\displaystyle S}$ ${\displaystyle C}$ ${\displaystyle B'}$
• 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. ${\displaystyle Q}$ ${\displaystyle B}$ ${\displaystyle S}$ ${\displaystyle C}$ ${\displaystyle B'}$

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:

1. Baryons with 3 u or d quarks are called N ( isospin ¹ ⁄ ₂ ) or Δ (isospin ³ ⁄ ₂ ).
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.
3. 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 .
4. Baryons with 0 u or d quarks are called Ω (isospin 0). Heavy quarks are identified by up to three subscriptions.
5. In the case of baryons, which decay due to the strong interaction , the mass is placed in brackets.
6. 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 . ${\displaystyle \mathrm {p} }$ ${\displaystyle {\bar {\mathrm {p} }}}$

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.

^(a)The masses of protons and neutrons are much more precisely known in atomic mass units (u) than in MeV / c ² . This is due to the relatively imprecisely known value of the elementary charge. In atomic mass units, the mass of the proton is 1.007 276 466 879 (91) u and that of the neutron 1.008 664 915 88 (49) u.

^(b)Greater than 10 ³⁵ years. See proton decay .

^(c)For free neutrons. Neutrons bound in stable atomic nuclei are stable.

^(d)The PDG indicates the decay width (Γ). The service life was calculated from this according to τ = ħ / Γ.

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. ${\displaystyle L_{2I,2J}}$ ${\displaystyle L}$ ${\displaystyle I}$ ${\displaystyle J}$ ${\displaystyle L_{I,2J}}$ ${\displaystyle J^{P}}$

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 ).
