Query: First Signs for String Breaking in Two-Flavor QCD   We have been examining the phenomenon of string breaking in QCD with two
flavors of dynamical staggered quarks. We construct a transfer matrix from a
combination of ``string'' and ``two-meson'' channels. Preliminary results with
low statistics show the expected signs of string breaking.
