Non-perturbative renormalisation of Delta F=2 four-fermion operators in two-flavour QCD
P. Dimopoulos, G. Herdoiza, F. Palombi +4
Using Schroedinger Functional methods, we compute the non-perturbative renormalisation and renormalisation group running of several four-fermion operators, in the framework of latt…
Weak low-energy couplings from topological zero-mode wavefunctions
P. Hernandez, M. Laine, C. Pena +3
We discuss a new method to determine the low-energy couplings of the weak Hamiltonian in the -regime. It relies on a matching of the topological poles in of three…
Precision computation of B_K in quenched lattice QCD
P. Dimopoulos, J. Heitger, C. Pena +2
We present the results of a precision computation of B_K with Wilson fermions. Simulations are performed at different lattice spacings, enabling continuum limit extrapolations. Two…
NLO anomalous dimension of multiplicatively renormalizable four-fermion operators in Schroedinger Functional schemes
Filippo Palombi, Carlos Pena, Stefan Sint
Renormalization constants for multiplicatively renormalizable parity-odd four-fermion operators are computed in various different Schroedinger Functional (SF) schemes and lattice r…
