在某些规范介导的超对称破缺模型中，在不完全的GUT多重态中，对希格斯势的辐射修正在重整化群运行期间被抵消。这允许相对较重的超伙伴和125 GeV的希格斯粒子，而微调仍然适度。在这封信中，我们证明了这种具有“焦点”行为的规范中介模型可以自然地嵌入到SU（5）× U（3）乘积群统一模型中。
In certain models of gauge-mediated supersymmetry breaking with messenger fields in incomplete GUT multiplets, the radiative corrections to the Higgs potential cancel out during renormalization group running. This allows for relatively heavy superpartners and for a 125 GeV Higgs while the fine-tuning remains modest. In this Letter, we show that such gauge mediation models with “focus point” behaviour can be naturally embedded into a model of SU (5)× U (3) product group unification.
