可观测扇区和隐扇区中离散对称性的公共规范起源

Common gauge origin of discrete symmetries in observable sector and hidden sector

Taeil Hur, Hye-Sung Lee, Christoph Luhn

摘要:

超阿贝尔规范对称性在超对称和非超对称的新物理模型中被激发出来。这种新的规范对称性可能与可观测扇区和隐藏扇区都相互作用。我们从共同的阿贝尔规范对称性出发,系统地研究了这两个部门中最普遍的剩余离散对称性。这些离散的对称性可以确保质子和候选暗物质的稳定性。一个隐藏的扇形暗物质候选者(最轻的U宇称粒子或LUP)通过规范玻色子Z '与标准模型场相互作用,规范玻色子Z'可以选择性地耦合到夸克或轻子。我们对离散对称性和轻子耦合暗物质候选者的含义进行了评论,最近由于DAMA和PAMELA结果的同时解释的可能性而突出了这一点。给出了对于给定的离散对称如何构造最一般的U(1)荷,并讨论了U(1)规范对称性与R宇称的关系。

英文摘要:

An extra Abelian gauge symmetry is motivated in many new physics models in both supersymmetric and nonsupersymmetric cases. Such a new gauge symmetry may interact with both the observable sector and the hidden sector. We systematically investigate the most general residual discrete symmetries in both sectors from a common Abelian gauge symmetry. Those discrete symmetries can ensure the stability of the proton and the dark matter candidate. A hidden sector dark matter candidate (lightest U-parity particle or LUP) interacts with the standard model fields through the gauge boson Z', which may selectively couple to quarks or leptons only. We make a comment on the implications of the discrete symmetry and the leptonically coupling dark matter candidate, which has been highlighted recently due to the possibility of the simultaneous explanation of the DAMA and the PAMELA results. We also show how to construct the most general U(1) charges for a given discrete symmetry, and discuss the relation between the U(1) gauge symmetry and R-parity.
