A NEW MODEL OF DIRECT GAUGE MEDIATION WITH AN AFFINE QUANTUM MODULI SPACE

We present a new, simple supersymmetry breaking model with direct gaug e mediation. Supersymmetry breaking sector is based on the model with an Affine quantum moduli space. The model has no gauge messengers and no light scalars charged under the Standard Model which give a negativ e contribution to the soft masses. Large expectation value at the mini mum is obtained by balancing the runaway potential and the dimension s ix nonrenormalizable term. This makes it easy to preserve the perturba tive unification. Enough suppression of the supergravity contribution to the soft masses can also be shown. (C) 1998 Elsevier Science B.V. A ll rights reserved.
