Hadrons with a heavy colour-adjoint particle

Abstract

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.
