Abstract

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.
