Transverse momentum as a measure of color topologies

Several distinct color flow topologies are possible in multiparton configurations. A method is proposed to find the correct topology, based on a minimization of the total transverse momentum of produced particles. This method is studied for three-jet Z0→q bar qg and four-jet W+W-→q1 bar q2q3 bar q4 events. It is shown how the basic picture is smeared, especially by parton-shower activity. The method, therefore, may not be sufficient on its own, but could still be a useful complement to others, and, e.g., help provide some handle on color rearrangement effects. copyright 1997 The American Physical Society
