Radiative correction of the correlator for (0^{++},1$^{-+}$) light   hybrid
  We calculate the radiative corrections to the current-current correlator of the hybrid current $g\bar q(x)\gamma_{\nu}iG_{\mu\nu}^aT^aq(x)$. Based on this new result we use the QCD sum rule approach to estimate lower bounds on the masses of the $J^{PC}$=$1^{-+}$ and $0^{++}$ light hybrids.
