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…
from twisted mass QCD
P. Dimopoulos, J. Heitger, C. Pena +2
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 advantag…
Quark bilinear step scaling functions and their continuum limit extrapolation
M. Guagnelli, J. Heitger, C. Pena +1
Some new results on nonperturbative renormalisation of quark bilinears in quenched QCD with Schroedinger Functional techniques are presented. Special emphasis is put on a study of…
Non-perturbative scale evolution of four-fermion operators
M. Guagnelli, J. Heitger, C. Pena +2
We apply the Schroedinger Functional (SF) formalism to determine the renormalisation group running of four-fermion operators which appear in the effective weak Hamiltonian of the S…
