Abstract
We present some preliminary results for at , using the twisted mass QCD formalism for the computation of bare matrix elements of the operator. The main advantage of the method is that mixing with other operators under renormalisation is avoided. Moreover the operator renormalisation is performed in the Schrödinger functional (SF) framework, using earlier results of our collaboration for the corresponding step scaling function.
