Abstract
We summarize four contributions about dynamical twisted mass fermions. The resulting report covers results for Nf=2 obtained from three different gauge actions, namely the standard Wilson plaquette gauge action, the DBW2 and the tree-level Symanzik improved gauge action. In addition, first results for Nf=2+1+1 flavours of twisted mass fermions are discussed.
