Abstract We reanalyze the 1?+ light hybrid from QCD sum rules with a Monte-Carlo based on uncertainty analysis. With 30% uncertainties in the accepted central values for QCD condensates and other input parameters, we obtain a prediction on the 1?+ hybrid mass of 1.71 ±0.22 GeV, which covers the mass of π1(1600). We also study the correlations between the input and output parameters of QCD sum rules.
