They are also classified as fermions, i.e., they have half-integer spin.
The most familiar baryons are protons and neutrons, both of which contain three quarks, and for this reason these particles are sometimes described as triquarks.
The neutron ... is a spin-½ fermion.
Protons are spin-1/2 fermions and are composed of three valence quarks, making them baryons (a sub-type of hadrons).
Quarks are fermionic particles of spin 1/2 (S = 1/2).
Because spin projections vary in increments of 1 (that is 1 ħ), a single quark has a spin vector of length 1/2, and has two spin projections (Sz = +1/2 and Sz = −1/2).
Two quarks can have their spins aligned, in which case the two spin vectors add to make a vector of length S = 1 and three spin projections (Sz = +1, Sz = 0, and Sz = −1).
If two quarks have unaligned spins, the spin vectors add up to make a vector of length S = 0 and has only one spin projection (Sz = 0), etc.
Since baryons are made of three quarks [DISPUTED], their spin vectors can add to make a vector of length S = 3/2, which has four spin projections (Sz = +3/2, Sz = +1/2, Sz = −1/2, and Sz = −3/2), or a vector of length S = 1/2 with two spin projections ...
Exotic baryons containing five quarks (known as pentaquarks) have also been discovered and studied.
