| Date | 2004-01 |
| Description | The recently developed Symanzik-improved staggered-quark discretization allows unquenched lattice-QCD simulations with much smaller (and more realistic) quark masses than previously possible. To test this formalism, we compare experiment with a variety of nonperturbative calculations in QCD drawn from a restricted set of ‘‘gold-plated'' quantities. We find agreement to within statistical and systematic errors of 3% or less.We discuss the implications for phenomenology and, in particular, for heavy-quark physics. |
