Mass spectrum of 1 − + exotic mesons from lattice QCD

Abstract

Time correlation functions of a hybrid exotic meson operator, with J = 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 π1(1400) and π1(1600), and also… (More)
