关于在LAr探测器中探测非常低质量的黑洞

About detecting very low mass black holes in LAr detectors

Ionel Lazanu, Sorina Lazanu, Mihaela Pârvu

摘要:

暗物质的性质仍然是一个悬而未决的问题。最简单的假设是,引力是唯一肯定与暗物质耦合的力,因此微型黑洞可能是一个可行的候选者。我们研究了直接探测质量在普朗克尺度(10 $^{-5}$ g)附近和以上的微型黑洞的可能性,确保在下一代巨大的LAr探测器中对这些物体进行经典引力处理。我们表明,在LAr产生的信号(电离和闪烁),使微黑洞或其他粒子之间的歧视。预计这些微黑洞的轨迹将出现在整个活动介质中,在任何方向上,在所有路径上产生均匀的电离和闪烁。

英文摘要:

The nature of dark matter is still an open problem. The simplest assumption is that gravity is the only force coupled certainly to dark matter and thus the micro black holes could be a viable candidate. We investigated the possibility of direct detection of micro black holes with masses around and upward the Planck scale (10$^{-5}$ g), ensuring classical gravitational treatment of these objects in the next generation of huge LAr detectors. We show that the signals (ionization and scintillation) produced in LAr enable the discrimination between micro black holes or other particles. It is expected that the trajectories of these micro black holes will appear as crossing the whole active medium, in any direction, producing uniform ionization and scintillation on all the path.
