Title:	Calculation of almost all energy levels of baryons
Authors:	Souza, Mario Everaldo de
Issue Date:	2011
Resumo :	It is considered that the effective interaction between any two quarks of a baryon can beapproximately described by a simple harmonic potential. The problem is firstly solved inCartesian coordinates in order to find the energy levels irrespective of their angular mo-menta. Then, the problem is also solved in polar cylindrical coordinates in order to takeinto account the angular momenta of the levels. Comparing the two solutions, a correspon-dence is made between the angular momenta and parities for almost all experimentallydetermined levels. The agreement with the experimental data is quite impressive and, ingeneral, the discrepancy between calculated and experimental values is below 5%. A cou-ple of levels of ∆,N, Σ±, and Ω present discrepacies between 6.7% and 12.5% [N(1655),N(1440),N(1675),N(1685),N(1700),N(1710),N(1720),N(1990),N(2600), ∆(1700),∆(2000), ∆(2300), Σ±(1189), Λ(1520), Ω(1672) and Ω(2250)].
