Qcd Analysis

We describe the determination of the strong coupling constant [Formula: see text] and of the charm-quark mass mc(mc) in the [Formula: see text]-scheme, based on the QCD analysis of the unpolarized World deep-inelastic scattering data. At NNLO the values of [Formula: see text] and [Formula: see text] are obtained and are compared with other determinations, and also clarifying discrepancies.

Pseudo Scalar

Tadpole improved Wilson quark actions with clover terms on anisotropic lattices are studied numerically. Using asymmetric lattice volumes, the pseudo-scalar meson dispersion relations are measured for 8 lowest lattice momentum modes with quark mass values ranging from the strange to the charm quark with various values of the gauge coupling β and 3 different values of the bare speed of light parameter ν. These results can be utilized to extrapolate or interpolate to obtain the optimal value for the bare speed of light parameter νopt(m) at a given gauge coupling for all bare quark mass values m. In particular, the optimal values of ν at the physical strange and charm quark mass are given for various gauge couplings. The lattice action with these optimized parameters can then be used to study physical properties of hadrons involving either light or heavy quarks.
