Improved Determination of the Mass of the $1^{-+}$ Light Hybrid Meson From QCD Sum Rules

H. Y. Jin, J. G. Korner, T. G. Steele

We calculate the next-to-leading order (NLO) ${\alpha }_s$-corrections to the contributions of the condensates $<\alpha G^2>$ and $<\bar{q}q{>}^2$ in the current-current correlator of the hybrid cu…
