%0 Journal Article %T Is There a Third Companion of Lambda and Sigma0? %A A. V. Kopylov %J Physics %D 2000 %I arXiv %X The comparison of magnetic moments of neutron and proton reveals three possible states of a nucleon each composed of quark plus diquark. In this scheme for the quark content uds there should be three baryons with a different structure: ud+s, us+d, ds+u. So one can expect the existence of a third companion to the known baryons Lambda and Sigma0. %U http://arxiv.org/abs/hep-ph/0005237v1
