Gaugino mass dependence of electron and neutron electric dipole moments

Unless squarks and sleptons are in the multi-TeV region or above, CP violat ing induced electric dipole moments of elementary particles can pose signif icant puzzles for supersymmetric (SUSY) models. We study the dipole-moment- inducing one-loop amplitudes as a function of the fundamental SUSY paramete rs and show that these puzzles are removed if there is a sufficiently large hierarchy between the gaugino masses and the scalar mass. We comment on th e experimental status of the low gaugino mass scenario. (C) 2000 Elsevier S cience B.V. All rights reserved.
