Lists of Baryons
These lists detail all known and predicted baryons in total angular momentum J = 1⁄2 and J = 3⁄2 configurations with positive parity.
- 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.
- Baryons composed of two types of quarks (uud, uus, ...) can exist in both J = 1⁄2 and J = 3⁄2 configurations
- Baryons composed of three types of quarks (uds, udc, ...) can exist in both J = 1⁄2 and J = 3⁄2 configurations. Two J = 1⁄2 configurations are possible for these baryons.
The symbols encountered in these lists are: I (isospin), J (total angular momentum), P (parity), u (up quark), d (down quark), s (strange quark), c (charm quark), b (bottom quark), Q (charge), B (baryon number), S (strangeness), C (charm), B′ (bottomness), as well as a wide array of subatomic particles (hover for name). (See the baryon article for a detailed explanation of these symbols.)
Antiparticles are not listed in the tables; however, they simply would have all quarks changed to antiquarks (and antiquarks changed to quarks), and Q, B, S, C, B′, would be of opposite signs. Particles with † next to their names have been predicted by the Standard Model but not yet observed. Values in red have not been firmly established by experiments, but are predicted by the quark model and are consistent with the measurements.

Famous quotes containing the words lists of and/or lists:
“Most of our platitudes notwithstanding, self-deception remains the most difficult deception. The tricks that work on others count for nothing in that very well-lit back alley where one keeps assignations with oneself: no winning smiles will do here, no prettily drawn lists of good intentions.”
—Joan Didion (b. 1934)
“Behold then Septimus Dodge returning to Dodge-town victorious. Not crowned with laurel, it is true, but wreathed in lists of things he has seen and sucked dry. Seen and sucked dry, you know: Venus de Milo, the Rhine or the Coloseum: swallowed like so many clams, and left the shells.”
—D.H. (David Herbert)
