Abstract
We give the prediction for the ground and excited state masses of the charmonium hybrid mesons, 1-+, 0+-, 0--, with exotic quantum numbers. We employ improved gluon and quark actions on anisotropic lattice, which reduce greatly the lattice artifacts, and lead to good signals. The data are extrapolated to the continuum limit, with finite size effects under well control. The ground state masses of 1-+, 0+-, 0-- agree with our earlier results, where the mass of 0-- were shown for the first time. And the excited state masses, reported for the first time here, are 6.450(190)GeV, 6.629(138)GeV and 8.487(201)GeV respectively.
