摘要

我们从一个被打破成 SU(5)gauge × U(1)X 和一个孪生 SU(5)gauge × U(1)X 的 E8 × E8 异质模型开始，其中一个 SU(5) 及其谱被确定为可见扇面，而另一个可以被确定为隐藏的孪生扇面。在这两种情况下，我们都得到了威尔逊线对称性破缺后的最小超对称标准模型（MSSM）谱，它由低能量R-奇偶性和{\mathbb{Z}}_4^R \）对称性增强。我们认为，在这个模型中不会有任何可观测到的质子衰变。

The absence of observable proton decay in a global SU(5) F-theory model

We begin with an E₈ × E₈ Heterotic model broken to an SU(5)_gauge × U(1)_X and a twin SU(5)_gauge × U(1)_X, where one SU(5) and its spectrum is identified as the visible sector while the other can be identified as a hidden twin sector. In both cases we obtain the minimal supersymmetric standard model (MSSM) spectrum after Wilson-line symmetry-breaking enhanced by a low energy R-parity and \( {\mathbb{Z}}_4^R \) symmetry. We argue that there will not be any observable proton decay in this model.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
