A New Model of Direct Gauge Mediation with an Affine Quantum Moduli Space
Nobuhito Maru
Abstract
We present a new, simple supersymmetry breaking model with direct gauge 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 negative contribution to the soft masses. Large expectation value at the minimum is obtained by balancing the runaway potential and the dimension six nonrenormalizable term. This makes it easy to preserve the perturbative unification. Enough suppression of the supergravity contribution to the soft masses can also be shown.
