Study of five quark system with three kinds of quark-quark hyperfine interaction
The low-lying energy spectra of five quark systems (I=1/2, S=0)
and (I=0, S=-1) are investigated with three kinds of schematic
interactions: the chromomagnetic interaction, the flavor-spin dependent
interaction and the instanton-induced interaction. In all the three models, the
lowest five quark state ( or ) has an orbital angular
momentum L=0 and the spin-parity ; the mass of the lowest
state is heavier than the lowest state
