Degeneracy Symmetry Of Baryon Spectra

Abstract

We present a data-supported new interpretation of the Rarita-Schwinger fields which reveals a well-defined pattern in the masses, spins, and parities of the N-, Delta -, and Lambda -hyperon excitations and which allows to probe the scale of the chiral phase transition for baryons. The degeneracy symmetry of the baryonic spectra emerges to be Isospin(x)Space- Time.
