Abstract
摘要
|
In present work, we investigate the spectrum of several low-lying sscqq^bar pentaquark configurations employing the constituent quark model, within which the hyperfine interaction between quarks is taken to be mediated by Goldstone boson exchange. Our numerical results show that four sscqq^bar configurations with J^P = 1/2^− or J^P = 3/2^− lie at energies very close to the recently observed five Omega_c^0 states by LHCb collaboration, this indicates that the sscqq^bar pentaquark configurations may form sizable components of the observed Omega_c^0 resonances. |
