New predictions on the mass of the $1^{-+}$ light hybrid meson from QCD sum rules

Zhuo-Ran Huang, Hong-Ying Jin, Zhu-Feng Zhang

We calculate the coefficients of the dimension-8 quark and gluon condensates in the current-current correlator of $1^{-+}$ light hybrid current $g\bar{q}(x){\gamma }_{\nu }i{G}_{\mu \nu }(x)q(x)$. Wi…
