WG V Conveners' Report: Charm Inputs for CKM Physics
H. Wittig, A. A. Petrov, D. G. Cassel
We introduce the contributions to the proceedings of Working Group V. The main topics were: present and future experiments dedicated to charm physics, the interplay between high-pr…
Fundamental parameters of QCD
Rainer Sommer, Hartmut Wittig
The theory of strong interactions, QCD, is described in terms of a few parameters, namely the strong coupling constant alpha_s and the quark masses. We show how these parameters ca…
Heavy quarks on the lattice: status and perspectives
Hartmut Wittig
The lattice method for the calculation of weak decay amplitudes of heavy quark systems is introduced. Results for leptonic and semi-leptonic decays of heavy mesons and …
Status and Prospects for Lattice Calculations in Heavy Quark Physics
Hartmut Wittig
The current status of lattice calculation of weak matrix elements for heavy quark systems is reviewed. After an assessment of systematic errors in present simulations, results for…
Lattice Results For Heavy Quark Physics
Hartmut Wittig
The status of lattice calculations for heavy quark systems is reviewed, focussing on weak matrix elements for leptonic and semi-leptonic decays of heavy mesons. After an assessment…
New Results From UKQCD Using the Cray T3D: Measuring Gluonic Observables
Hartmut Wittig
We report on a set of simulations performed at several values of the lattice spacing on the Cray T3D at Edinburgh. Different methods to extract the lattice scale from the static qu…
