衰变引力子暗物质中的反氘核

Antideuterons from Decaying Gravitino Dark Matter

Timur Delahaye, Michael Grefe

摘要:

我们研究了在双线性R-宇称破坏的情况下,通过估计在引力子衰变中可以产生的宇宙射线反氘的数量,来改善引力子暗物质寿命的约束的可能性。考虑到所有不同来源的理论不确定性,我们发现,超出宇宙射线反质子数据已经设定的限制的改进幅度是相当狭窄的,无法实现的下一代实验。然而,我们也确定了更有前途的能源范围为未来的实验。

英文摘要:

We study the possibility of improving the constraints on the lifetime of gravitino dark matter in scenarios with bilinear R-parity violation by estimating the amount of cosmic-ray antideuterons that can be produced in gravitino decays. Taking into account all different sources of theoretical uncertainties, we find that the margin of improvement beyond the limits already set by cosmic-ray antiproton data are quite narrow and unachievable for the next generation of experiments. However, we also identify more promising energy ranges for future experiments.
