英文摘要	We calculate the next-to-leading order (NLO) alpha(s) corrections to the contributions of the condensates and <(q) over barq>(2) in the current-current correlator of the hybrid current g (q) over bar (x)gamma(nu)iF(munu)(a)T(a)q(x) using the external field method in the Feynman gauge. After incorporating these NLO contributions into the Laplace sum rules, the mass of the J(PC)=1(-+) light hybrid meson is recalculated using the QCD sum rule approach. We find that the sum rules exhibit enhanced stability when the NLO alpha(s) corrections are included in the sum rule analysis, resulting in a 1(-+) light hybrid meson mass of approximately 1.6 GeV.
