利用低阈值直接探测实验探索光介质

Exploring light mediators with low-threshold direct detection experiments

Felix Kahlhoefer, Suchita Kulkarni, Sebastian Wild

摘要:

我们探讨了未来低温直接探测实验的潜力,以确定传递暗物质和原子核之间相互作用的介质的性质。由于它们的低阈值和大曝光量,像CRESST-III,SuperCDMS SNOLAB和EDELWEISS-III这样的实验将有很好的能力在MeV范围内为一大类模型重建介质质量。结合来自几个实验的信息进一步改进了参数重建,即使在考虑与背景不确定性和暗物质速度分布相关的附加干扰参数时。这些观测结果可能会提供有趣的可能性,研究暗物质的自我相互作用与直接检测实验。

英文摘要:

We explore the potential of future cryogenic direct detection experiments to determine the properties of the mediator that communicates the interactions between dark matter and nuclei. Due to their low thresholds and large exposures, experiments like CRESST-III, SuperCDMS SNOLAB and EDELWEISS-III will have excellent capability to reconstruct mediator masses in the MeV range for a large class of models. Combining the information from several experiments further improves the parameter reconstruction, even when taking into account additional nuisance parameters related to background uncertainties and the dark matter velocity distribution. These observations may offer the intriguing possibility of studying dark matter self-interactions with direct detection experiments.
