Twisted mass QCD for weak matrix elements
Carlos Pena
I report on the application of tmQCD techniques to the computation of hadronic matrix elements of four-fermion operators. Emphasis is put on the computation of in quenched QC…

Non-perturbative renormalisation of left-left four-fermion operators with Neuberger fermions
P. Dimopoulos, L. Giusti, P. Hernandez +5
We outline a general strategy for the non-perturbative renormalisation of composite operators in discretisations based on Neuberger fermions, via a matching to results obtained wit…
