标题： Split families unified

摘要： 我们提出一个简单的分裂族超对称模型，该模型符合味极限，并保留了规范耦合统一的成功预测，并自然解释了希格斯质量。 该模型在标准模型的味层次结构、超对称味问题、统一和希格斯质量之间建立了复杂的联系。 特别是，统一倾向于通过希格斯势中四次耦合的D项修正自然地产生较大的希格斯质量。 通过稳定的质子，统一尺度被降低，这可以解释b-τ费米子耦合统一的成功。 除了需要适度轻的停止子以实现可行的电弱对称破缺外，超粒子谱与自然超对称性相似，这是由超对称味问题和最近的LHC限制所驱动的。 最后，希格斯产生和衰变、NLSP衰变以及扩展标准模型规范群至TeV尺度以上的新状态为LHC上的实验搜索提供了信号。 显示英文摘要

摘要： We present a simple supersymmetric model of split families consistent with flavor limits that preserves the successful prediction of gauge coupling unification and naturally accounts for the Higgs mass. The model provides an intricate connection between the Standard Model flavor hierarchy, supersymmetric flavor problem, unification and the Higgs mass. In particular unification favors a naturally large Higgs mass from D-term corrections to the quartic couplings in the Higgs potential. The unification scale is lowered with a stable proton that can account for the success of b-tau Yukawa coupling unification. The sparticle spectrum is similar to that of natural supersymmetry, as motivated by the supersymmetric flavor problem and recent LHC bounds, with a heavy scalar particle spectrum except for a moderately light stop required for viable electroweak symmetry breaking. Finally, Higgs production and decays, NLSP decays, and new states associated with extending the Standard Model gauge group above the TeV scale provide signatures for experimental searches at the LHC.
