摘    要:给出光子的夸克uF+2/3(或dF+1/3)和它的超对称性伴子ye,B^-2/3(或ye,B^+1/3)由胶子弦粘合在一起的夸克-胶子结构,分析光子的结构函数.所得光子结构与实验观测事实相符;光子结构函数在动量分数x=2.5×10^-3时没有出现象质子结构函数那样的上升迹象,其原因可能是uF^+2/3的超对称性伴子ye,B^-2/3质量标度很高所致.

关 键 词:光子  结构函数  宇宙早期粒子  超对称性伴子  大质量标度

Abstract:The quark-gluon structure of a photon that quark uF+2/3(or dF^-1/3) and its supersymmetry companion ye,B^-2/3 (or ye,B^+1/3 ) glueing by gluon-strings is given, the structure function of a photon is analysed. The results from this structure coincide with the experiments. At the momentum function x = 2.5 × 10^-3 ,the rising sign of the structure function similar to that of protons can't be seen. The large mass scale of the supersymmetry companion may be the reason.
Keywords:photon   structure function   early universe particles   supersymmetry companions   large mass scale
