摘要

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.
