Revisiting 1-＋ Light Hybrid from Monte-Carlo Based QCD Sum Rules

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 7rl...

Description
Summary: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 7rl （1600）. We also study the correlations between the input and output parameters of QCD sum rules.
