P-wave Ωb states: masses and pole residues

In this study, we consider all P-wave Omega(b) states represented by interpolating currents with a derivative and calculate the corresponding masses and pole residues using the QCD sum rule method. Because of the large uncertainties in our calculation compared with the small difference in the masses of the excited Omega(b) states observed by the LHCb collaboration, it is necessary to study other properties of the P-wave Omega(b) states represented by the interpolating currents investigated in the present work to gain a better understanding of the four excited Omega(b) states observed by the LHCb collaboration.

Automated summary

In this study, the masses and pole residues of P-wave Omega(b) states represented by interpolating currents with a derivative are calculated using the QCD sum rule method. The uncertainties in the calculation are large compared to the small difference in the masses of the excited Omega(b) states observed by the LHCb collaboration, thus further investigation is necessary to understand other properties of the P-wave Omega(b) states represented by the interpolating currents studied in this work.
