用ARGO-YBJ测量的3-3000 TeV能区的Cosmic Ray p+He能谱

The Cosmic Ray p+He energy spectrum in the 3-3000 TeV energy range measured by ARGO-YBJ

S. M. Mari, P. Montini

摘要:

ARGO-YBJ实验是羊八井国际宇宙线观测站运行的全覆盖空气簇射探测器。自2007年11月至2013年2月,探测器一直处于稳定的数据采集状态。高海拔和高分割和时空分辨率提供了在非常宽的范围内探索宇宙线能谱的可能性,从几TeV到PeV区域。高分段允许详细测量横向分布,这可以用来区分轻元素和重元素产生的簇射。在这项工作中,我们提出的宇宙线光分量谱的能量范围为3-3000 TeV的测量。已进行了分析,通过使用基于贝叶斯定理的二维展开方法。

英文摘要:

The ARGO-YBJ experiment is a full coverage air shower detector operated at the Yangbajing International Cosmic Ray Observatory. The detector has been in stable data taking in its full configuration since November 2007 to February 2013. The high altitude and the high segmentation and spacetime resolution offer the possibility to explore the cosmic ray energy spectrum in a very wide range, from a few TeV up to the PeV region. The high segmentation allows a detailed measurement of the lateral distribution, which can be used in order to discriminate showers produced by light and heavy elements. In this work we present the measurement of the cosmic ray light component spectrum in the energy range 3-3000 TeV. The analysis has been carried out by using a two-dimensional unfolding method based on the Bayes' theorem.
