用精确的希格斯物理学探索统一

Probing Unification With Precision Higgs Physics

Sibo Zheng

摘要:

我们提出了一种新的方法,通过在LHC的希格斯汤川耦合的精确测量探测大统一。这个想法是很好的动机,有效的运营商的外观不抑制的质量尺度统一$M_{\rm{U}}$在现实的统一模型与汤川部门的最小结构。这样的运营商修改希格斯汤川耦合在相关模式的规模$M_{\rm{U}}$,举行了高阶修正。相干性分析表明,在弱尺度下,τ Yukawa耦合相对于其标准模型值的偏差是第三代Yukawa耦合中最大的。这个特征,如果被未来的大型强子对撞机验证,可以作为统一的暗示。

英文摘要:

We propose a novel approach of probing grand unification through precise measurements on the Higgs Yukawa couplings at the LHC. This idea is well motivated by the appearance of effective operators not suppressed by the mass scale of unification $M_{\rm{U}}$ in realistic models of unification with the minimal structure of Yukawa sector. Such operators modify the Higgs Yukawa couplings in correlated patterns at scale $M_{\rm{U}}$ that hold up to higher-order corrections. The coherences reveal a feature that, the deviation of tau Yukawa coupling relative to its standard model value at the weak scale is the largest one among the third-generation Yukawa couplings. This feature, if verified by the future LHC, can serve as a hint of unification.
