论文摘要
假定由太阳捕获的o(tev)质量的重的暗物质颗粒$ ϕ $可能会腐烂到相对论的轻米粒子(MCP)。这些MCP可以通过Icecube检测器测量。 MCP的无质量隐藏光子模型与核相互作用,因此可以在ICECUBE上评估预期的MCP和中微子的数量和通量。基于以下假设:在6年内在IceCube上没有观察到任何事件,因此在90 \%C. l中计算了MCP通量的相应上限。这些结果表明,当Icecube的次级能量范围O(100GEV)-O(100GEV)-O(10TEV)act iCecube上可以直接检测到MCP,当时$ε^2 \ gtr.gtr.gtr.gtr.gtr. gtremim10^$ 10}。以及一个0.6 MeV <$ M_ {MCP} $ <10 MEV和$ 6 \ times10^{ - 6} $ <$ <$ <$ε$ $ $ $ $ $ 10^{ - 4} $的新区域在$ M_ {MCP} $ - $ε$飞机中排除在ICECUBE 6年的数据中。
It is assumed that heavy dark matter particles $ϕ$ with O(TeV) mass captured by the Sun may decay to relativistic light milli-charged particles (MCPs). These MCPs could be measured by the IceCube detector. The massless hidden photon model was taken for MCPs to interact with nuclei, so that the numbers and fluxes of expected MCPs and neutrinos may be evaluated at IceCube. Based on the assumption that no events are observed at IceCube in 6 years, the corresponding upper limits on MCP fluxes were calculated at 90\% C. L.. These results indicated that MCPs could be directly detected in the secondaries' energy range O(100GeV)-O(10TeV) at IceCube, when $ε^2\gtrsim10^{-10}$. And a new region of 0.6 MeV < $m_{MCP}$ < 10 MeV and $6\times10^{-6}$ < $ε$ $\lesssim$ $10^{-4}$ is ruled out in the $m_{MCP}$-$ε$ plane with 6 years of IceCube data.
