| 英文摘要 | Mass spectra and wave functions of the JP = (bcq) baryons are calculated by the relativistic Bethe Salpeter equation (BSE) with considering the mixing effects between the 1+ and 0+ (bc)-diquarks inside, Based on the diquark picture, the three -body problem of baryons is transformed into two two -body problems. The BSE and wave functions of the 0+ diquark are given, and then solved numerically to obtain the effective mass spectra and form factors. Also we present the wave functions at zero point for the (bc)diquark. Considering the obtained diquark form factors, the (bcq) baryons are then described by the BSE as the bound state of a diquark and a light quark, where the interaction kernel includes the inner transitions between the 0+ and 1+ diquarks. The general wave function of the 1+ (bcq) baryons is constructed and solved to obtain the corresponding mass spectra. Especially, by using the obtained wave functions, the mixing effects between Ebc(S2b,) and E;,c(S2icc) in ground states are computed and determined to be small( 1%). The numerical results indicate that it is a good choice to take Ebc and E as the baryon states with the inside (bc)-diquarks occupying the definite spin. |
