论文摘要
使用在皮埃尔螺旋钻天文台收集的数据，我们搜索了偶然的诱导过程的签名，这些签名将提供银河系中超重颗粒的证据。这种颗粒本可以在通货年后的时期足够产生，以匹配当今推断的暗物质的丰度。这些签名的非观察使我们能够探测intsanton强度并得出有史以来从intsanton介导的过程中获得的最好的界限，这是在黑暗扇区中减小的量规交互的耦合常数：$α_x\ lyssim 0.09 $，价格为$ 10^{9}} {9} {9} \ simsim m______} $ gm，
Using data collected at the Pierre Auger Observatory, we search for signatures of instanton-induced processes that would provide evidence of super-heavy particles decaying in the Galactic halo. Such particles could have been produced sufficiently during the post-inflationary epoch to match the relic abundance of dark matter inferred today. The non-observation of these signatures allows us to probe the instanton strength and to derive a bound, the best ever obtained from instanton-mediated processes, on the reduced coupling constant of gauge interactions in the dark sector: $α_X \lesssim 0.09$, for $10^{9} \lesssim M_X/{\rm GeV} < 10^{19}$.
