摘要
以Schwinger粒子产生机制为基础,在忽略了狄拉克方程中的高阶修正项后,导出了QCD过程中正反夸克对的产生几率与产率,给出了K+与π+粒子的产额比,与高能粒子碰撞中的实验结果相比较表明,理论与实验符合得很好.
With the Schwinger mechanism of particle production as a basis, after neglecting the high-order correction item in Dirac equation, the authors derive out the pair production probability and rate of quark and antiquark in QCD processes, present the number ratio of K^+ to π^+. It is shown from comparing with experimental measurements in high-energy particle collisions that the theoretical results fit well with experimental data.
