β¦ Synopsis
We summarize our measurement of the mass of the exotic l-+ hybrid meson using an improved Kogut-Susskind action. We show results from both quenched and dynamical quark simulations and compare with results from Wilson quarks. Extrapolation of these results to the physical quark mass allows comparison with experimental candidates for the l-+ hybrid meson.

The spectral properties of hybrid meson interpolating fields are investigated. The quantum numbers of the meson are carried by smeared-source fermion operators and highly-improved chrome-electric and -magnetic field operators composed with APE-smeared links. The effective masses of standard and hybr
