اثرات بر هم‌کنش فوق ریز بر جرم باریونهای N و Δ

Presenting a model for theoretical study of baryon masses, either in relativistic or nonrelativistic area, has always been of great importance and several suggestions have been proposed. On the other hand, taking into account the effects of hyperfine interactions leads to interesting results. In the present work, we first introduce the hyperfine interaction and the quark potential corresponding to the isospin interaction. We then obtain the wavefunctions as well as the corresponding eigenvalues. The obtained results for the spectrum of baryons show a good agreement with experimental results.
