We discuss the spectrum of hadrons with a heavy color-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.
