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…

Precision for B-meson matrix elements

Damiano Guazzini, Rainer Sommer, Nazario Tantalo

We demonstrate how HQET and the Step Scaling Method for B-physics, pioneered by the Tor Vergata group, can be combined to reach a further improved precision. The observables consid…

Light quark masses and pseudoscalar decay constants from Nf=2 Lattice QCD with twisted mass fermions

B. Blossier, Ph. Boucaud, P. Dimopoulos +15

We present the results of a lattice QCD calculation of the average up-down and strange quark masses and of the light meson pseudoscalar decay constants with Nf=2 dynamical fermions…

Flavour symmetry restoration and kaon weak matrix elements in quenched twisted mass QCD

P. Dimopoulos, J. Heitger, F. Palombi +3

We simulate two variants of quenched twisted mass QCD (tmQCD), with degenerate Wilson quarks of masses equal to or heavier than half the strange quark mass. We use Ward identities…

Dynamical Twisted Mass Fermions with Light Quarks

Ph. Boucaud, P. Dimopoulos, F. Farchioni +19

We present results of dynamical simulations with 2 flavours of degenerate Wilson twisted mass quarks at maximal twist in the range of pseudo scalar masses from 300 to 550 MeV. The…

QCD with light Wilson quarks on fine lattices (II): DD-HMC simulations and data analysis

L. Del Debbio, L. Giusti, M. Lüscher +2

In this second report on our recent numerical simulations of two-flavour QCD, we provide further technical details on the simulations and describe the methods we used to extract th…
