相对论粒子在二维库仑场中的散射

Scattering of relativistic particles by a Coulomb field in two dimensions

Qiong-gui Lin

摘要:

研究了二维库仑场$\pm Ze^2/r$对相对论狄拉克粒子的散射,得到了散射振幅的分波级数。对于小的$Z$,级数可以近似求和,给出一个封闭的形式。这个结果虽然近似,但具有一些非微扰的性质,不能从树层次的微扰量子电动力学中得到。

英文摘要:

The scattering of relativistic Dirac particles by a Coulomb field $\pm Ze^2/r$ in two dimensions is studied and the scattering amplitude is obtained as a partial wave series. For small $Z$ the series can be summed up approximately to give a closed form. The result, though being aproximate, exhibites some nonperturbative feature and cannot be obtained from perturbative quantum electrodynamics at the tree level.
