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