一种新的与晕无关的暗物质直接探测分析方法

A new halo-independent approach to dark matter direct detection analysis

Brian Feldstein, Felix Kahlhoefer

摘要:

局部暗物质速度分布的不确定性是直接探测实验数据分析中的一个关键难点。在这里,我们提出了一种新的方法来处理这种不确定性,它不涉及任何假设的暗物质晕的结构。给定一个暗物质模型,我们的方法产生的速度分布,最好地描述了一组直接检测数据作为一个有限的流与优化的速度和密度的总和。该方法概念简单,数值上非常有效。我们给出了一个明确的例子中,该方法被应用到确定质子的比例中子耦合的暗物质从一组假设的未来数据。

英文摘要:

Uncertainty in the local dark matter velocity distribution is a key difficulty in the analysis of data from direct detection experiments. Here we propose a new approach for dealing with this uncertainty, which does not involve any assumptions about the structure of the dark matter halo. Given a dark matter model, our method yields the velocity distribution which best describes a set of direct detection data as a finite sum of streams with optimised speeds and densities. The method is conceptually simple and numerically very efficient. We give an explicit example in which the method is applied to determining the ratio of proton to neutron couplings of dark matter from a hypothetical set of future data.
