摘要：

We study the nonstrange and strangeonium light hybrid mesons with JPC = 2+- by using the method of QCD sum rules. The local hybrid interpolating currents with three Lorentz indices are constructed to couple to such exotic quantum numbers. We calculate the correlation functions up to dimension eight condensates at the leading order of alpha s. In our results, the masses of the nonstrange b2 and h2 hybrids are about 2.65 GeV, while that of the strangeonium h'2 hybrid is about 2.72 GeV. Such exotic 2+- hybrids can be generated through both the two-gluon and three-gluon emission processes in the radiative decays of chi cJ. Moreover, these hybrid mesons may be detectable due to their peculiar decay behaviors and small decay widths. Using the high-statistics data samples of psi(3686) in BESIII and BelleII, it is possible to hunt for such hybrid states through the partial wave analyses in the b2 -> omega/a1/h1/a2 pi -> 4 pi, h2 -> rho pi -> 3 pi, and h2 -> b1 pi -> 5 pi processes.
