We discuss the spectrum of hadrons with a heavy colour-adjoint particle -motivated by the gluino of supersymmetry. Using the lattice approach, we explore in detail the gluonic bound states -the 'glueballino' or 'gluelump'. We also make a first determination of the spectrum of the 'adjoint mesons' -which have a light quark and antiquark bound to the heavy adjoint particle. A comparison of the spectra of these two systems is also made.

Lattice QCD with $N_f=2$ flavours of sea quark is used to explore the spectrum and decay of a $J^{PC}=1^{-+}$ spin-exotic hybrid meson. We test lattice determination of S-wave decay amplitudes at threshold using $b_1 \to \pi \omega$ where agreement with data is found. We find a hybrid meson state at 2.2(2) GeV with a partial width to $\pi b_1$ of 400(120) MeV and to $\pi f_1$ of 90(60) MeV.Comment: 16 pages, 4 ps figures, version accepted for publication in Phys Rev
