论文摘要
我们研究了直接检测暗物质颗粒(例如暗光子)出现在上层大气上的前景。最近的一项工作将平流层的爆发样温度偏移与〜38-47 km的高度相关联,与事件无关流媒体物质有关。令人惊讶的是,如果它们构成当地DM密度的一部分,则深色光子与该工作中提出的推理相匹配。深色光子与具有相同总能量的真实光子混合,而无需外部场与轴所需的外部磁场混合。此外,平流层上方的电离层等离子体柱可以增强由于共振引起的暗光子转换。平流层很容易通过气球飞行进入。可以很容易地组装带有多达几吨有效载荷的气球任务,以在如此大气的高度下运行1-2个月,从而使该提案后的现场直接直接DM搜索工作。该方法不必局限于流式深色光子,因为可以同时搜索其他DM候选者。在多波段探测器系统中结合不同类型的测量和/或将此类研究与其他并发的大气观测相关联,例如从空间中,可能被证明是直接DM检测中缺失的新方法。
We investigate the prospects for direct detection of Dark Matter (DM) particles, such as dark photons, incident on the upper atmosphere. A recent work relates the burst-like temperature excursions in the stratosphere at heights of ~38-47 km with incident invisible streaming matter. Surprisingly, dark photons match the reasoning presented in that work provided they constitute part of the local DM density. Dark photons mix with real photons with the same total energy without the need for an external field as would be required for instance for axions. Furthermore, the ionospheric plasma column above the stratosphere can enhance the dark photon to photon conversion due to resonance. The stratosphere is easily accessible via balloon flights. Balloon missions with up to a few tons of payload can be readily assembled to operate for 1-2 months at such atmospheric heights making for realistic short term endeavor of on-site direct DM search following this proposal. The approach need not be limited to streaming dark photons as other DM candidates might be searched simultaneously. Combining different types of measurements in a multi-band detector system and/or relating such investigations with other concurrent atmospheric observations, e.g. from space, may be proven to be the missing new approach in direct DM detection.
