Light hybrid baryons in QCD sum rules

High Energy Physics - Phenomenology 2025-07-25 v1

Abstract

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 N1/2N_{1/2^-} and Δ1/2\Delta_{1/2^-} states, while the positive-parity ones are much heavier. We suggest to search for these light hybrid baryons via the χcJ/Υ\chi_{cJ}/\Upsilon decay processes in the future.
