Kaon B-parameter with NF=2 dynamical Wilson fermions

F. Mescia, V. Gimenez, V. Lubicz +3

We present a preliminary study of the neutral kaon mixing bag parameter BK using two flavors of dynamical Wilson fermions. We determine the matrix element of the relevant DeltaS=2…

Cutoff effects in maximally twisted LQCD

Giancarlo Rossi, Roberto Frezzotti, Guido Martinelli +1

The Symanzik analysis of correlators in lattice QCD with maximally twisted Wilson fermions reveals that there exist cutoff artifacts which tend to become large as the quark mass ge…

The UTfit Collaboration Report on the Status of the Unitarity Triangle beyond the Standard Model I. Model-independent Analysis and Minimal Flavour Violation

UTfit Collaboration, M. Bona, M. Ciuchini +10

Starting from a (new physics independent) tree level determination of rhobar and etabar, we perform the Unitarity Triangle analysis in general extensions of the Standard Model with…

The Ademollo-Gatto theorem for lattice semileptonic decays

Damir Becirevic, Guido Martinelli, Giovanni Villadoro

We present the results of the calculation of the Kl3 semileptonic form factor at zero momentum transfer, f(0), obtained at one-loop in partially quenched Chiral Perturbation Theory…

Rare Kaon Decays on the Lattice

Gino Isidori, Guido Martinelli, Paolo Turchetti

We show that long distance contributions to the rare decays K -> pi nu nu-bar and K -> pi l+ l- can be computed using lattice QCD. The proposed approach requires well established m…

Reducing cutoff effects in maximally twisted lattice QCD close to the chiral limit

R. Frezzotti, G. Martinelli, M. Papinutto +1

When analyzed in terms of the Symanzik expansion, lattice correlators of multi-local (gauge-invariant) operators with non-trivial continuum limit exhibit in maximally twisted latti…

The 2004 UTfit Collaboration Report on the Status of the Unitarity Triangle in the Standard Model

UTfit Collaboration, M. Bona, M. Ciuchini +9

Using the latest determinations of several theoretical and experimental parameters, we update the Unitarity Triangle analysis in the Standard Model. The basic experimental constrai…
