标题： TOPOLOGICAL DEFECTS AND HIGHEST ENERGY COSMIC AND GAMMA RAYS

摘要： 本文回顾了关于宇宙射线通量的假设，即在大约$10^{19}\eV$以上的能区，可观测到的部分宇宙射线可能由大统一能量尺度下早期宇宙相变遗留下来的拓扑缺陷的衰变或湮灭产生（$\approx10^{16}\GeV$）。 我们讨论了可能的宇宙射线产生缺陷模型的特征信号，这些信号在未来可以进行实验检验。 我们重点关注的是对预测的粒子通量普遍谱性质的模型无关分析。 显示英文摘要

摘要： In this paper we review the hypothesis that a considerable part of the cosmic ray flux observed above about $10^{19}\eV$ may be produced by decaying or annihilating topological defects left over from phase transitions in the early universe at grand unification energy scales ($\approx10^{16}\GeV$). Possible signatures of cosmic ray producing defect models are discussed which could be tested experimentally in the near future. We thereby focus on model independent universal spectral properties of the predicted particle fluxes.
