So you can have an isospin multiplet defined for proton and neutron (both are spin 1/2), or for positive, neutral and negative pions (scalars, spin 0). Isospin is the simplest case in which we built isospin representation out of just u and d flavors.

WebIn particle and nuclear physics, isospin, I or I3, is a quantum number related to the strong nuclear force. Isospin is associated with a conservation law that requires strong interaction decays to conserve isospin. This term was derived from isotopic spin, but physicists prefer the term isobaric spin, which is more precise in meaning. WebAug 14, 2024 · Isospin was introduced before the quark-model was developed. Since up- and down-quarks have about the same mass and the same coupling to the strong force, this symmetry works pretty well for nucleons (proton u u d, neutron u d d ). S U ( 2) was proposed as an analogy to regular spin.
