人类赖以生存的地球时刻经受着来自外太空中高能粒子的轰击,这些粒子包括各种原子核、正负电子、高能伽马射线和中微子等,统称为宇宙线。宇宙线被认为起源于超新星爆炸的遗迹或黑洞吸积等极端天体,因而它们也是极端条件下天体环境和物理规律的信使。人类对宇宙线的观测和研究已长达一个世纪,而时至今日,关于宇宙线的起源、加速机制以及它们在宇宙空间中的传播及相互作用等基本问题尚未得到彻底的解答。宇宙线的数目随能量变化的...

Measurement of the antiproton/proton ratio in the few-TeV energy range with ARGO-YBJ
Measurement antiproton/proton ratio few-TeV energy range ARGO-YBJ
2011/1/5
Cosmic ray antiprotons provide an important probe for the study of cosmic ray propagation in the interstellar space and to investigate the existence of Galactic dark matter.
We show that a hydrodynamical expansion leads in a natural way to the observed “ridge” structure in the two particle correlation function versus the pseudorapidity difference and the azimuthal angl...
