具有混合宇称和标准模型耦合的类希格斯标量可能是潜在的无质量SU(5)统一的进一步证据

A Higgs-Like Scalar With Mixed-Parity and Standard-Model-Like Couplings Could be Further Evidence for Underlying Massless SU(5) Unification

摘要:

QUD(SU(5)规范理论,具有无质量的左手5 + 15 + 40 + 45* 费米子)的束缚态S矩阵可能是标准模型成功的基础。QUD顶夸克的动力学作用导致了两个类似希格斯的标量共振,其中的eta_6 -再现了标准模型的顶事件,而eta_3 -可能具有~ 125 GeV的质量。弱相互作用参与动力学意味着共振不是宇称本征态,因此应该有赝标和标量电弱耦合。此外,树么正性条件也成立,部分原因是电弱物理振幅与微扰理论的接近,部分原因是它与regge行为的密切关系。这意味着这两种共振的物理耦合可以与标准模型的希格斯玻色子相媲美。与孤立的标准模型不同,QUD的基本统一意味着不会有LHC的“噩梦般的场景”,相反,一个广泛的,广泛的,实验性的计划最终应该被实施。

英文摘要:

The bound-state S-Matrix of QUD (SU(5) gauge theory with massless left-handed 5 + 15 + 40 + 45* fermions) might underly the success of the Standard Model. The dynamical role of the QUD top quark leads to two Higgs-like scalar resonances, the eta_6 - which reproduces Standard Model top events, and the eta_3 - which could have a mass ~ 125 GeV. The participation of the weak interaction in the dynamics implies the resonances are not parity eigenstates and so should have pseudoscalar and scalar electroweak couplings. Also, a tree-unitarity condition could hold - in part because of the closeness of the electroweak physical amplitudes to perturbation theory, and - in part because of the intimate relation with regge behavior. This would imply that the combined physical couplings of the two resonances are comparable to those of the Standard Model Higgs boson. Unlike the isolated Standard Model, the underlying unification of QUD implies there will be no LHC "nightmare scenario" and that, instead, a broad, extensive, experimental program should, eventually, be implemented.
