Light hybrid baryons in QCD sum rules
Light hybrid baryons in QCD sum rules
We have calculated the mass spectra of nucleon and delta hybrid baryons with both positive-parity and negative-parity by using the method of QCD sum rules. We predicte that the lowest-lying hybrid baryons are the negative-parity $N_{1/2^-}$ and $Î_{1/2^-}$ states, while the positive-parity ones are much heavier. We suggest to search for these light hybrid baryons via the $Ï_{cJ}/Î¥$ decay processes in the future.
