中性SU(2)标准模型的规范扩展和矢量玻色子暗物质候选

Neutral SU(2) Gauge Extension of the Standard Model and a Vector-Boson Dark-Matter Candidate

J. Lorenzo Diaz-Cruz, Ernest Ma

摘要:

如果把粒子相互作用的标准模型推广到包含中性SU(2)_N规范因子,使SU(3)_C x SU(2)_L x U(1)_Y x SU(2)_N嵌入E_6或[SU(3)]^3中,则可能出现守恒的广义R宇称。结果,我们得到了可能的暗物质候选者X_1的第一个例子,它是一个非阿贝尔因矢量玻色子。使用目前的数据,它的质量预计将小于约1 TeV。这个模型的相关Z',以及希格斯扇区的一些特征,应该可以在大型强子对撞机(LHC)上观察到。

英文摘要:

If the standard model of particle interactions is extended to include a neutral SU(2)_N gauge factor, with SU(3)_C x SU(2)_L x U(1)_Y x SU(2)_N embedded in E_6 or [SU(3)]^3, a conserved generalized R parity may appear. As a result, we have the first example of a possible dark-matter candidate X_1 which is a non-Abelain vector boson. Using current data, its mass is predicted to be less than about 1 TeV. The associated Z' of this model, as well as some signatures of the Higgs sector, should then be observable at the LHC (Large Hadron Collider).
