2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/161064We discuss the recent progress in computing the D-meson decay constant and D->pi l nu form factors from the lattice QCD simulations with Nf=2 dynamical using Wilson quarks. We report fD=201(20)MeV and F+(1GeV^2)/fD=4.04(78)GeV^-1 at a=0.08fm.Contribution to the proceedings of Moriond 2008 : QCD and High Energy Interactions sessionHigh Energy Physics - LatticeHigh Energy Physics - Phenomenologytext
