Heavy Hybrids from NRQCD

Abstract

We present results for the exotic $0^{+-}$ and $1^{-+}$ $b\bar{b}g$ hybrids at $\beta=6.0$. A leading order NRQCD action is used to generate the heavy quark propagators. The optimisation of operators is discussed and we compare our results to the predictions of recent potential calculations.Comment: 3 pages, four figures, Latex, uses espcrc2.sty.
