SPARTICLE SPECTRUM AND DARK-MATTER IN M-THEORY

The phenomenological implications of the eleven dimensional limit of M -theory (strongly coupled E-8 x E-8) are investigated. In particular w e calculate the supersymmetric spectrum subject to constraints of corr ect electroweak symmetry breaking and the requirement that the lighest supersymmetric particle provides the dark matter of the universe. The B-soft term associated with the generation of a mu term in the superp otential is calculated and its phenomenology is discussed. (C) 1998 El sevier Science B.V. All rights reserved.
