Abstract
We study hybrid mesons from the clover and improved gauge actions atβ = 2.6 on the anisotropic 12 3 × 36 lattice using our PC cluster. We estimate the mass of 1 −+ light quark hybrid as well as the mass of the charmonium hybrid. The improvement of both quark and gluonic actions, first applied to the hybrid mesons, is shown to be more efficient in reducing the lattice spacing and finite volume errors.
