Takaaki Nomura, Hiroshi Okada

摘要:

本文讨论了在伴随表象中引入具有非零超荷的$SU(2)_H$二重态费米子和标量场的局部隐$SU(2)_H$和标准模型$SU(2)_H$中连接规范场项的一圈生成.在伴随的标量场发展真空期望值之后,我们得到了$SU(2)_H$和$U(1)_Y$规范场之间的动力学混合项。我们说明了这样一个具体的情况下,在紫外线(UV)完成与本地$SU(2)_H$对称性的标量双峰是我们的暗物质候选人和它的稳定性是由剩余的$Z_2$对称性从$SU(2)_H$保证暗物质模型。残余密度的暗物质的计算集中的情况下,暗物质湮灭到已知的粒子通过$SU(2)_H$规范与辐射诱导动力学混合的相互作用。

英文摘要:

We discuss one loop generation of the term connecting gauge fields from a local hidden $SU(2)_H$ and the standard model $U(1)_Y$ introducing an $SU(2)_H$ doublet fermion with non-zero hypercharge and a scalar field in adjoint representation. Then we obtain a kinetic mixing term between $SU(2)_H$ and $U(1)_Y$ gauge fields after the adjoint scalar field developing vacuum expectation value. We illustrate such a concrete scenario introducing a dark matter model in an ultraviolet (UV) completion with local $SU(2)_H$ symmetry where the scalar doublet is our dark matter candidate and its stability is guaranteed by remnant $Z_2$ symmetry from $SU(2)_H$. Relic density of dark matter is calculated focusing on the case in which dark matter annihilate into known particles via $SU(2)_H$ gauge interactions with radiatively induced kinetic mixing.
