在西藏羊八井（海拔4300 m）的ARGO-YBJ实验中，自2007年10月以来一直在收集数据。在这里，我们提出了一些重要的结果，在伽玛射线天文学和宇宙射线物理学。重点放在从点状源（蟹状星云，MRK 421）的伽马射线发射的分析，对反质子/质子通量比的初步限制，对大规模的宇宙射线各向异性和质子-空气截面。还讨论了探测器的性能，并概述了实验的前景。
The ARGO-YBJ experiment at YangBaJing in Tibet (4300 m a.s.l.) has been taking data with its full layout since October 2007. Here we present a few significant results obtained in gamma-ray astronomy and cosmic-ray physics. Emphasis is placed on the analysis of gamma-ray emission from point-like sources (Crab Nebula, MRK 421), on the preliminary limit on the antiproton/proton flux ratio, on the large-scale cosmic-ray anisotropy and on the proton–air cross-section. The performance of the detector is also discussed, and the perspectives of the experiment are outlined.
