超弱相互作用暗物质的最小步行技术
Superweakly interacting dark matter from the Minimal Walking Technicolor
摘要:
我们研究了一个超弱相互作用的暗物质粒子的最小步行的彩色理论的动机。我们的WIMP是一个无菌状态和一个带有标准模型第四族中微子电荷的状态的混合物。我们表明,该模型可以给出正确的数量的暗物质的范围内的WIMP质量和混合角。我们计算边界的模型参数从当前的加速器数据,包括倾斜校正的精密电弱参数,以及从低温实验,超级神冈和冰立方实验。我们表明,一致的暗物质的解决方案存在,满足所有当前的约束。然而,模型的几乎整个参数范围都在下一代实验的组合范围内。
英文摘要:
We study a superweakly interacting dark matter particle motivated by minimal walking technicolor theories. Our WIMP is a mixture of a sterile state and a state with the charges of a standard model fourth family neutrino. We show that the model can give the right amount of dark matter over a range of the WIMP mass and mixing angle. We compute bounds on the model parameters from the current accelerator data including the oblique corrections to the precision electroweak parameters, as well as from cryogenic experiments, Super-Kamiokande and from the IceCube experiment. We show that consistent dark matter solutions exist which satisfy all current constraints. However, almost the entire parameter range of the model lies within the the combined reach of the next generation experiments.
