Abstract

We consider focus point gauge mediation within the framework of the next-to-minimal supersymmetric standard model, which substantially reduces the degree of finetuning for the electroweak symmetry breaking. The milder fine-tuning is realized by a messenger field in the adjoint representation of SU(5) gauge group with SU(3)c octet being heavy. Our model has a simple ultraviolet completion. The fine-tuning measure Δ can be as small as 40-50 without any contradiction with LHC constraints.
