“…where M s from [10] and in the conversion to the MS scheme the known 4-loop anomalous dimensions of quark masses and coupling [20,21] together with Λ MS from [10] were used. For the D-meson decay constants, we adopt again fit ansätze linear in m 2 π (and a 2 ), while for f D we also model the sea quark dependence in a fit form inspired by partially quenched heavy meson chiral perturbation theory (HMχPT) [22,23], treating the charm quark as heavy, viz.…”

We present a computation of the charm quark's mass and the leptonic D-meson decay constants f D and f D s in two-flavour lattice QCD with non-perturbatively O(a) improved Wilson quarks. Our analysis is based on the CLS configurations at two lattice spacings (a = 0.065 and 0.048 fm, where the lattice scale is set by f K ) and pion masses ranging down to ∼ 190 MeV at Lm π 4, in order to perform controlled continuum and chiral extrapolations with small systematic uncertainties.

All lattices have dimensions T ×L 3 with T = 2L.

Determination of strange sea quark distributions from fixed-target and collider data

We present an improved determination of the strange sea distribution in the nucleon with constraints coming from the recent charm production data in neutrino-nucleon deep-inelastic scattering by the NOMAD and CHORUS experiments and from charged current inclusive deep-inelastic scattering at HERA. We demonstrate that the results are consistent with the data from the ATLAS and the CMS experiments on the associated production of W AE -bosons with c-quarks. We also discuss issues related to the recent strange sea determination by the ATLAS experiment using LHC collider data.
