Abstract
Lattice QCD with flavours of sea quark is used to explore the spectrum and decay of a spin-exotic hybrid meson. We test lattice determination of -wave decay amplitudes at threshold using where agreement with data is found. We find a hybrid meson state at 2.2(2) GeV with a partial width to of 400(120) MeV and to of 90(60) MeV.
