The baryon octet in the light of the alpha/beta rule for exact calculation of particle masses. — •Karl Otto Greulich — Fritz-Lipmann Institut, Beutenbergstr.11, 07745 Jena
The baryon octet arranges eight prominent elementary particles (nucleons, Lambda, Sigma and Omega baryons) according to their strangeness "S" and their Isospin. In the present contribution it is shown that their masses can be calculated with an accuracy of better than 1 % by the equation:
m = m(proton) + 70,04 MeV/c2 (S2 +1,5)
For the neutral and charged Sigma baryon the additive term is 2 and 2,5. Here it is shown that the mass m0 = 70,04 MeV/c2 is predicted by simple equations for accurate calculation of particle masses (K.O. Greulich 2010 J Mod Phys, 1, 300-302), particularly by the alpha/beta rule ( K.O. Greulich, 2016 DPG Spring meeting, Hamburg, T 99.4). This is exactly the mass of a fictive particle with the classical electron radius as de Broglie wavelength.
