S. Ambrosanio et Ae. Nelson, NEW MULTISCALE SUPERSYMMETRIC MODELS WITH FLAVOR-CHANGING NEUTRAL-CURRENT SUPPRESSION, Physics letters. Section B, 411(3-4), 1997, pp. 283-291
We discuss the phenomenology of a class of supersymmetric models in wh
ich some of the quark and lepton superfields are an integral part of a
dynamical supersymmetry breaking sector. The corresponding squarks an
d sleptons are much heavier than any other superpartners, and could na
turally have masses as high as similar to 40 TeV. We discuss a general
set of conditions for acceptable flavor-changing neutral currents and
natural electroweak symmetry breaking, and identify two particularly
interesting new classes of theories. We discuss how phenomenological s
ignatures of such multi-scale models at the CERN LEP IT and Fermilab T
evatron colliders could significantly differ from previously considere
d scenarios. In particular, we give experimental signals which could b
e present if the left-handed selectron is much lighter than the right-
handed one. (C) 1997 Elsevier Science B.V.
