摘要：
Time correlation functions of a hybrid exotic meson operator, with J(PC)=1(-+), generated in quenched lattice QCD are subjected to a (Bayesian) maximum entropy analysis. Five distinct spectral levels are uncovered. Their extrapolation into the physical pion mass region suggests a possible relationship to experimentally known states pi(1)(1400) and pi(1)(1600), and also to a state in the 2 GeV region carrying the same quantum numbers.
