      abstract     = {We present results of our ongoing determination of "string
                      breaking" in quantum chromodynamics (QCD) including two
                      dynamical light quarks. Our investigation of the fission of
                      the string between a heavy (static) quark and a
                      corresponding antiquark into a meson-antimeson system is
                      based on dynamical configurations of size 24(3) x 40. The
                      all-to-all light quark propagators occurring in the
                      transition element are computed from a set of 200 low-lying
                      eigenmodes of the Hermitian Wilson-Dirac matrix which
                      encodes the effect of the dynamical quarks. These eigenmodes
                      are calculated on the 1312-node IBM p690 system at the John
                      von Neumann Institute in Julich. Combining the eigenvalue
                      computations with a variety of ground state enhancing
                      optimization methods we determine the matrix elements of the
                      two-by-two system with so far unprecedented accuracy. We
                      observe-for the first time ever in a simulation of
                      4-dimensional lattice-QCD-level-splitting as the perfect
                      signature for dynamical string breaking between ground state
                      and excited potential. (c) 2005 Elsevier B.V. All rights
