Study of $qqqc\bar{c}$ five quark system with three kinds of quark-quark hyperfine interaction

S. G. Yuan, K. W. Wei, J. He +2

The low-lying energy spectra of five quark systems $uudc\bar{c}$ (I=1/2, S=0) and $udsc\bar{c}$ (I=0, S=-1) are investigated with three kinds of schematic interactions: the chromom…
