Abstract

The phenomenological implications of the M-theory limit in which supersymmetry is broken by the F-terms of five-brane moduli is investigated. In particular we calculate the supersymmetric spectrum subject to constraints of correct electroweak symmetry breaking. We find interesting differences especially in the squark sector compared with $M$-theory scenarios with standard embedding and weakly-coupled Calabi-Yau compactifications in the large $T$-limit.
