引力介导的发光暗物质

Lightening Gravity-Mediated Dark Matter

Yoo-Jin Kang, Hyun Min Lee

摘要:

我们重新审视了一个大质量的自旋2粒子的情况下,任意自旋的暗物质和标准模型之间的通信介质。在有效理论中考虑自旋为2的粒子的一般耦合,讨论了暗物质具有不同通道的热产生机制和暗物质的自散射。对于WIMP和轻暗物质的情况下,我们施加的遗物密度条件和各种实验约束,从直接和间接的检测,精密测量以及对撞机实验。我们表明,它是重要的,包括湮灭的暗物质到一对自旋2粒子在允许和禁止的制度,从而打开了一致的参数空间暗物质。自旋2介质的基准模型的上下文中的翘曲额外的维度和简化模型进行比较。

英文摘要:

We revisit the scenario of a massive spin-2 particle as the mediator for communicating between dark matter of arbitrary spin and the Standard Model. Taking the general couplings of the spin-2 particle in the effective theory, we discuss the thermal production mechanisms for dark matter with various channels and the dark matter self-scattering. For WIMP and light dark matter cases, we impose the relic density condition and various experimental constraints from direct and indirect detections, precision measurements as well as collider experiments. We show that it is important to include the annihilation of dark matter into a pair of spin-2 particles in both allowed and forbidden regimes, thus opening up the consistent parameter space for dark matter. The benchmark models of the spin-2 mediator are presented in the context of the warped extra dimension and compared to the simplified models.
