摘要
The phenomenological implications of the 11-dimensional limit of M-theory (strongly coupled E-8 x E-8) are investigated, In particular we calculate the supersymmetric particle spectrum subject to constraints of correct electroweak symmetry breaking and the requirement that the lightest supersymmetric particle provides the dark matter of the universe. We also calculate direct detection event rates of the lightest neutralino relevant for non-baryonic dark matter experiments. The modulation effect, due to Earth's annual motion is also calculated, (C) 1999 Elsevier Science B.V. All rights reserved.
