    "abstract": "Mass differences between octet strange baryons, octet and decuplet strange\nbaryons, and nonet vector mesons and octet baryons of equal strangeness\ncoincide (within the small experimental uncertainties) with the levels of a\nrecently proposed hadron mass spectrum. A number, M, characterises the mass\ndifference in relation to the strange quark mass of the spectrum. The mass\ndiference of Lambda and Sigma0 (delta I=1) is characterised by M=+1. The mass\ndifference of Sigma0 and Sigma(1385)0 (delta J=1) is characterised by M=-1.\nVector meson-baryon (delta J=1/2) mass differences are characterised by M=-1/2.\nThe mass differences of strange decuplet baryon resonances (delta S=1) are\ncharacterised by M=-2 and M=-3, where M is equal to the strangeness of the more\nmassive baryon.",
