论文摘要
我们介绍了一个$ su（2）_x^{} $ Dark Sector，而无需任何费用，然后在黑暗$ su（2）_x^{} $ GAUGE字段与标准模型$ su（2）_l^{} {} \ times u（times u（times u（times u（times u（times u（times u（times u（1）_y）_y^）$ GAUGE} $ GAUGE}）$ GAUGE {} $ GAUGE} $ GAUGE}）之间。虽然一个暗规玻色子变成了深色光子，但其他玻色子可以保持稳定以形成暗物质粒子。如果将来观察到深色光子和暗物质，则可以测试几乎变性的暗光子和暗物质。
We introduce an $SU(2)_X^{}$ dark sector without any fermions and then realize a non-abelian kinetic mixing between the dark $SU(2)_X^{}$ gauge fields and the standard model $SU(2)_L^{}\times U(1)_Y^{}$ gauge fields. While one of the dark gauge bosons becomes a dark photon, the others can keep stable to form a dark matter particle. The nearly degenerate masses of dark photon and dark matter could be tested if the dark photon and the dark matter are both observed in the future.
