重新考虑地震学对宏观暗物质可用参数空间的约束
Reconsidering seismological constraints on the available parameter space of macroscopic dark matter
摘要:
利用月震数据,提出了宏观暗物质(宏)可用参数空间的约束条件。我们表明,实际的限制是相当弱的,通过更详细地考虑机制,宏观影响产生可检测的地震波,其波长远长于宏观的直径。我们表明,目前的地震学证据可以排除的宏观参数空间的一部分是相当小的比以前报道的,特别是,候选人大于或等于核密度不排除月球地震。
英文摘要:
Using lunar seismological data, constraints have been proposed on the available parameter space of macroscopic dark matter (macros). We show that actual limits are considerably weaker by considering in greater detail the mechanism through which macro impacts generate detectable seismic waves, which have wavelengths considerably longer than the diameter of the macro. We show that the portion of the macro parameter space that can be ruled out by current seismological evidence is considerably smaller than previously reported, and specifically that candidates with greater than or equal to nuclear density are not excluded by lunar seismology.
