An improved Standard Model prediction of BR(B→τν) and its implications for New Physics
Abstract The recently measured B → τ ν branching ratio allows to test the Standard Model by probing virtual effects of new heavy particles, such as a charged Higgs boson. The accuracy of the test isExpand

Flavour physics and Lattice QCD: averages of lattice inputs for the Unitarity Triangle Analysis
We review recent results of Lattice QCD calculations relevant for flavour physics. We discuss in particular the hadronic parameters entering the amplitudes of K0-K0bar, D0-D0bar and B0-B0bar mixing,Expand

Pseudoscalar decay constants of kaon and D-mesons from N f = 2 twisted mass Lattice QCD
We present the results of a lattice QCD calculation of the pseudoscalar meson decay constants fπ, fK, fD and fDs, performed with Nf = 2 dynamical fermions. The simulation is carried out with theExpand

Charged Lepton Flavour Violation and (g-2)(mu) in the Littlest Higgs Model with T-Parity: A Clear Distinction from Supersymmetry
We calculate the rates for the charged lepton flavour violating decays l_i -> l_j gamma, tau -> l pi, tau -> l eta, tau -> l eta', mu^- -> e^- e^+ e^-, the six three body leptonic decays tau^- ->Expand

Leading isospin-breaking corrections to pion, kaon and charmed-meson masses with Twisted-Mass fermions
We present a lattice computation of the isospin-breaking corrections to pseudoscalar meson masses using the gauge configurations produced by the European Twisted Mass collaboration with $N_f = 2 + 1Expand

Mass of the b quark and B -meson decay constants from Nf=2+1+1 twisted-mass lattice QCD
We present precise lattice computations for the b-quark mass, the quark mass ratios m(b)/m(c) and m(b)/m(s) as well as the leptonic B-decay constants. We employ gauge configurations with fourExpand

QED corrections to hadronic processes in lattice QCD
In this paper, for the first time to our knowledge, a method is proposed to compute electromagnetic effects in hadronic processes, such as decays, using lattice simulations. The method can beExpand

Rare and CP-Violating K and B Decays in the Littlest Higgs Model with T-Parity
We calculate the most interesting rare and CP-violating K and B decays in the Littlest Higgs model with T-parity. We give a collection of Feynman rules including v 2 =f 2 contributions that areExpand

The K→π vector form factor at zero momentum transfer on the lattice
Abstract We present a quenched lattice study of the form factors f + ( q 2 ) and f 0 ( q 2 ) of the matrix elements 〈 π | s ¯ γ μ u | K 〉 . We focus on the second-order SU(3)-breaking quantity [ 1 −Expand
