Abstract

We have studied exotic hybrid mesons, made from a quark, an antiquark and gluons. Here we summarize a quenched calculation at 6/g² = 5.85 and 6.15. We investigate both the light quark hybrids and the charmonium hybrids. These mesons are found to mix with four-quark states, and this mixing can be used to help in extracting masses from the propagators.
