In this Letter we analyze the consequences, for the LHC, of gauge and third family Yukawa coupling unification with a particular set of boundary conditions defined at the grand unified theory (GUT) scale, which we characterize as effective "mirage" mediation. We perform a global χ2 analysis including the observables M(W), M(Z), G(F), α(em)(-1), α(s)(M(Z)), M(t), m(b)(m(b)), M(τ), BR(B→X(s)γ), BR(B(s)→μ(+)μ(-)), and M(h). The fit is performed in the minimal supersymmetric standard model in terms of 10 GUT scale parameters, while tanβ and μ are fixed at the weak scale. We find good fits to the low energy data and a supersymmetry spectrum which is dramatically different than previously studied in the context of Yukawa unification.
在这封信件中，我们分析了规范和第三族 Yukawa 耦合在特定的边界条件下与大统一理论 (GUT) 尺度统一的后果，我们将其描述为有效的“幻影”介导。我们进行了全局 χ2 分析，包括可观测量 M(W)、M(Z)、G(F)、α(em)(-1)、α(s)(M(Z))、M(t)、m(b)(m(b))、M(τ)、BR(B→X(s)γ)、BR(B(s)→μ(+)μ(-))和 M(h)。拟合是在最小超对称标准模型中进行的，涉及 10 个 GUT 尺度参数，而 tanβ 和 μ 则固定在弱尺度上。我们发现对低能数据的拟合很好，并且得到了与之前在 Yukawa 统一背景下研究的截然不同的超对称谱。
