A Model with Simultaneous Dynamical Breaking of Supersymmetry and GUT   Gauge Symmetry
  We try to construct a model in which supersymmetry and grand unified gauge symmetry are dynamically broken at the same time. In this model SUSY breaking is mediated mainly by massive vector multiplet, and a new solution for the mu problem is proposed.
