Abstract
We use the method of QCD sum rules to study the -wave charmed and bottom baryons of the flavor and calculate their masses up to the order with the heavy-quark mass. Our results suggest that the can be well interpreted as a -wave state, and it probably has a partner state close to it. Our results also suggest that there may exist as many as four -wave states in the energy region 3.3–3.5 GeV, and we propose to search for them in the future LHCb and BelleII experiments.
