Abstract

We summarize our results concerning the spectrum and mass anomalous dimension\nof SU(2) gauge theories with various numbers of fermions in the adjoint\nrepresentation, where each Majorana fermion corresponds effectively to half a\nDirac flavour N_f. The most relevant examples for extensions of the standard\nmodel are supersymmetric Yang-Mills theory (N_f=1/2) and Minimal Walking\nTechnicolour (N_f=2). In addition to these theories we will also consider the\ncases of N_f=1 and N_f=3/2. The results comprise the particle spectrum of\nglueballs, triplet and singlet mesons, and possible fractionally charged spin\nhalf particles. In addition we will discuss our recent results for the mass\nanomalous dimension.\n
