论文摘要
基于4年AMS-02抗蛋白质数据，我们在暗物质（DM）歼灭横截面上介绍了一些代表性最终状态通道的质量。我们使用最新的宇宙射线传播模型，对实验和理论错误的现实处理，以及基于最新的Pythia代码发布的输入抗蛋白子光谱的更新计算。我们发现报告的DM信号的提示在统计学上是微不足道的。对错误的适当处理对于可靠的结论至关重要。 DM灭绝的抗抗原界是最严格的抗抗原界，将热DM探测为TEV量表。边界对传播模型的依赖性和DM光晕曲线也进行了量化。当应用于7年AMS-02数据集时，初步估计得出了类似的结论，但也提出了谨慎的谨慎，即未来对DM过量的可能索赔。
Based on 4 yr AMS-02 antiproton data, we present bounds on the dark matter (DM) annihilation cross section vs. mass for some representative final state channels. We use recent cosmic-ray propagation models, a realistic treatment of experimental and theoretical errors, and an updated calculation of input antiproton spectra based on a recent release of the PYTHIA code. We find that reported hints of a DM signal are statistically insignificant; an adequate treatment of errors is crucial for credible conclusions. Antiproton bounds on DM annihilation are among the most stringent ones, probing thermal DM up to the TeV scale. The dependence of the bounds upon propagation models and the DM halo profile is also quantified. A preliminary estimate reaches similar conclusions when applied to the 7 years AMS-02 dataset, but also suggests extra caution as for possible future claims of DM excesses.
