确定暗物质 (DM) 质量对于了解暗物质至关重要。 <?format ?>我们提出了一种新颖的 DM 速度分布参数化方法，这将允许使用弱相互作用大质量粒子 (WIMP) 直接检测实验的数据来准确测量 DM 质量 <?format ?>。具体来说，我们将速度分布的自然对数参数化为速度的多项式。我们使用即将进行的实验的模拟数据证明，通过拟合 WIMP 质量和相互作用截面以及多项式系数，我们可以准确地重建 WIMP 质量和速度分布。这种新方法首次证明，无需事先假设分布函数，就可以准确、无偏地重建 WIMP 质量。我们预计这项技术在分析未来的实验数据中将具有无价的价值。
Determining the dark matter (DM) mass is of paramount importance for understanding dark matter. <?format ?>We present a novel parametrization of the DM speed distribution which will allow the DM mass to <?format ?>be accurately measured using data from weakly interacting massive particle (WIMP) direct detection experiments. Specifically, we parametrize the natural logarithm of the speed distribution as a polynomial in the speed. We demonstrate, using mock data from upcoming experiments, that by fitting the WIMP mass and interaction cross section, along with the polynomial coefficients, we can accurately reconstruct both the WIMP mass and speed distribution. This new method is the first demonstration that an accurate, unbiased reconstruction of the WIMP mass is possible without prior assumptions about the distribution function. We anticipate that this technique will be invaluable in the analysis of future experimental data.
