The Physics Society of Iran Iranian Journal of Physics Research 1682-6957 9 2 2019 11 26 Effects of hyperfine interactions on masses of N and Δ baryons Effects of hyperfine interactions on masses of N and Δ baryons 209 213 818 FA H Hassanabadi S Zarrinkamar AA Rajabi Journal Article 2019 11 26 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.
