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 $N_{1\mathrm{/}{2}^{-}}$ and ${\mathrm{\Delta }}_{1\mathrm{/}{2}^{-}}$ states, while the positive-parity ones are much heavier. We suggest to search for these light hybrid baryons via the ${\chi }_{cJ}\mathrm{/}\mathrm{{\rm Y}}$ decay processes in the future.
