Determination of the weak Hamiltonian in the SU(4) chiral limit through topological zero-mode wave functions

P. Hernandez, M. Laine, C. Pena +3

A new method to determine the low-energy couplings of the weak Hamiltonian is presented. It relies on a matching of the topological poles in of three-point correlato…

Non-perturbative renormalisation of four-fermion operators in N_f=2 QCD

P. Dimopoulos, G. Herdoiza, F. Palombi +4

We present results for the non-perturbative renormalisation of four-fermion operators with two flavours of dynamical quarks. We consider both fully relativistic left current-left c…

First quenched results for the matrix elements of the B_{B_s} mixing parameter in the static limit from tmQCD

F. Palombi, M. Papinutto, C. Pena +1

We report on a non-perturbative study of the scale-dependent renormalization factors of a multiplicatively renormalizable basis of Delta B=2 parity-odd four-fermion operators in qu…

Non-perturbative renormalization of static-light four-fermion operators in quenched lattice QCD

Filippo Palombi, Mauro Papinutto, Carlos Pena +1

We perform a non-perturbative study of the scale-dependent renormalization factors of a multiplicatively renormalizable basis of parity-odd four-fermion operators in quenc…

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…

B0-B0bar mixing in the static approximation from the Schroedinger Functional and twisted mass QCD

F. Palombi, M. Papinutto, C. Pena +1

We discuss the renormalisation properties of parity-odd Delta B=2 operators with the heavy quark treated in the static approximation. Via twisted mass QCD (tmQCD), these operators…
