Abstract

The full spatial distribution of the color fields of two and four static quarks is measured in lattice SU~2! field theory at separations up to 1 fm at b52.4. The four-quark case is equivalent to a qq¯qq¯ system in SU~2! and is relevant to meson-meson interactions. By subtracting two-body flux tubes from the four-quark distribution we isolate the flux contribution connected with the four-body binding energy. This contribution is further studied using a model for the binding energies. Lattice sum rules for two and four quarks are used to verify the results.
