Description

In this work I will summarize our results concerning the spectrum and mass anomalous dimension of SU(2) gauge theories with a different number of fermions in the adjoint representation, where each Majorana fermion corresponds effectively to half a Dirac flavour $N_f$. The most relevant examples for the 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 I will also consider the cases of $N_f=1$ and $N_f=3/2$. The results will contain the particle spectrum of glueballs, triplet and singlet mesons, and possible fractionally charged spin half particles. In addition I will discuss our recent results for the mass anomalous dimension.
