在Glauber多重散射理论框架下,利用混合夸克模型,计算了K^+-d弹性散射的总截面,并与实验数据比较,探讨普通夸克与奇异夸克质量差异及夸克自由度对散射的影响。结果表明,质量差异对总散射的影响约为2%,夸克间相互作用在改善实验数据的理论描述中起着十分重要的作用。
In the Glauber theoretical framework the calculation of elastic K ^+ -d sattering cross section is performed in the hybrid quark-hadron model. Compared with experimental data, the results show that the quark degrees of freedom play an important role in explaining available experimental data and the mass difference has effect on sattering cross section about 2%.
