Re-analysis of the baryon mass spectrum using the quark shell model

Detailed numerical comparison of the baryon mass spectrum analysis of Jones, Levi Setti and Lasinski with that of Horgan has led to a deeper understanding of the formulae and techniques used in both analyses. In this light, we have re-analysed the baryon mass spectrum for the (70, 1^?)₁ and (56/70, 2⁺)₂ multiplets updated to include the most recent PDG data and have checked the results for the (70, 1^?)₁ using two independent computer programmes. The predicted spectra obtained are presented and the classification of the states is compared with that of a recent decay analysis by Hey, Litchfield and Cashmore.
