P-wave Ω b states: masses and pole residues * *Supported by the National Natural Science Foundation of China (11675263)

Abstract

In this study, we consider all P-wave 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 states observed by the LHCb collaboration, it is necessary to study other properties of the P-wave states represented by the interpolating currents investigated in the present work to gain a better understanding of the four excited states observed by the LHCb collaboration.
