QCD sum rule calculation for P-wave bottom baryons

We study the P-wave bottom baryons using the method of QCD sum rule and heavy quark effective theory. Our results suggest that Lambda(b) (5912)(0) and Lambda(b) (5920)(0) can be well described by the baryon doublet [(3) over bar (F), 1, 1, rho], and they belong to the SU(3) IF multiplets of J(P) = 1/2(-) and 3/2(-). Their SU(3) flavor partners, Xi(b)(1/2(-)) and Xi(b) (3/2(-)), have masses 6.06 +/- 0.13 GeV and 6.07 +/- 0.13 GeV, respectively, with mass splitting 9 * 4 McV. The results obtained using baryon doublet [(3) over bar (F), 1, 0, lambda] are similar and also consistent with the experimental data. We also study the SU(3) 6(F) multiplets by using the baryon multiplets [6(F), 0, 1, lambda], [6(F), 1, 0, rho] and [6(F), 2, 1, lambda], and our results suggest that the P-wave bottom baryons Sigma(b), Xi(b)' and Omega(b) have (averaged) masses of about 6.0 GeV, 6.2 GeV and 6.4 GeV, respectively.
