AstroParticle高能物理

AstroParticle Physics at the Highest Energies

Angela V. Olinto

摘要:

最近的国际努力使我们更接近揭开宇宙射线起源的百年之谜。宇宙射线、伽马射线和中微子观测站正在达到必要的灵敏度,以研究最高能量的宇宙加速器,并开始使用宇宙粒子研究实验室能量以上的粒子相互作用。已知的伽马射线源的数量已经增加了几个数量级。可能的宇宙射线源已经缩小了与脚踝和GZK一样的光谱特征在最高能量的确认。中等能量宇宙射线到达方向分布的各向异性显示了银河系复杂的局部邻域。在最高能量下,粒子天文学的曙光仍然是具有挑战性的,而与成分有关的测量则指向成分的变化或宇宙射线在高能下的相互作用。要想清楚地解开中微子能量之谜,需要大量增加宇宙射线和中微子观测的统计数据。

英文摘要:

Recent international efforts have brought us closer to unveiling the century old mystery of the origin of cosmic rays. Cosmic ray, gamma ray, and neutrino observatories are reaching the necessary sensitivity to study the highest energy cosmic accelerators and to begin the use of cosmic particles to study particle interactions above laboratory energies. The number of known gamma-ray sources has increased by orders of magnitude. Possible cosmic ray sources have narrowed down with the confirmation of an ankle and the GZK-like spectral feature at the highest energies. Anisotropies in the distribution of arrival directions of cosmic rays at intermediate energies show a complex local neighborhood of the Galaxy. At the highest energies the dawn of particle astronomy is still challenging while composition related measurements point to a change in the composition or the interaction of cosmic rays at ultrahigh energies. A clear resolution of the ultrahigh energy mystery calls for a significant increase in statistics of cosmic ray and neutrino observations.
