Abstract
Within the method of parity-projected QCD sum rules, we study the mass spectra of light hybrid baryons with πΌβ‘(π½π) =1/2β’(1/2Β±),3/2β’(1/2Β±),1/2β’(3/2Β±),3/2β’(3/2Β±) by constructing the local πβ’πβ’πβ’π interpolating currents. We calculate the correlation functions up to dimension eight condensates at the leading order of πΌπ . The stable QCD Lapalce sum rules can be established for the positive-parity π1/2+,Ξ3/2+,Ξ1/2+ and negative-parity π1/2β,π3/2β,Ξ1/2β channels to extract their mass spectra. The lowest-lying hybrid baryons are predicted to be the positive-parity π1/2+ state around 2.01 GeV. These hybrid baryons mainly decay into conventional baryon plus meson final states. We propose to search for the light hybrid baryons through the Ο/πβ‘(3686) decays via the three-gluon emission mechanism in BESIII and BelleII experiments. Hopefully, our studies of the light hybrid baryons will be useful for understanding the excited baryon spectrum and the behavior of gluonic degrees of freedom in QCD.
