摘要:

我们提出了一个具有奇异暗SU(2)规范群的矢量暗物质模型。引入两个希格斯三重态自发打破对称性。所有的暗规范玻色子都变得有质量,最轻的玻色子是可行的矢量DM候选者。它的稳定性由一个剩余的Z_2对称性保证。我们研究了Higgs测量数据、暗物质遗迹密度以及直接和间接探测实验对参数空间的约束。我们发现许多参数点满足所有的约束条件,他们可以在未来的实验中进一步测试。类似的方法可以用来从任意SO(N)规范群构造矢量暗物质模型。

英文摘要:

We propose a vector dark matter model with an exotic dark SU(2) gauge group. Two Higgs triplets are introduced to spontaneously break the symmetry. All of the dark gauge bosons become massive, and the lightest one is a viable vector DM candidate. Its stability is guaranteed by a remaining Z_2 symmetry. We study the parameter space constrained by the Higgs measurement data, the dark matter relic density, and direct and indirect detection experiments. We find numerous parameter points satisfying all the constraints, and they could be further tested in future experiments. Similar methodology can be used to construct vector dark matter models from an arbitrary SO(N) gauge group.
