摘要
在粒子物理最小超对称标准模型下，计算了Ｘ－０Ｘ－０→ｇｇ物理过程的反应截面．利用所获得的截面值给出了暗物质粒子ＮｅｕｔｒａｌｉｎｏＸ－０湮没生成的反质子谱．计算表明：反质子谱具有的可观性，为寻找暗物质粒子和超对称粒子提供了一种可能的途径．
The cross section of the process X-0X-0→gg is calculated in supersymmetry model of parti- cle physics. By means of the obtained cross section value, the estimate of source spectrum for anti- protons produced by neutralino X-0 annihilation is given. We conclude that the observation of this spectrum in the low energy region offers a possible approach to find the dark matter and the super- symmetry particle.
