四维电动力学中局域在畴壁上的不可消除的发散
On unremovable divergencies in four-dimensional electrodynamics localized on a domain wall
摘要：
本文考虑一个描述局域在畴壁上的费米子和规范场的模型。模型的零模部分再现了四维旋量电动力学。结果表明，在所得到的四维有效理论中，弹性$γγ$散射过程的最低阶重正化振幅由于高阶模的贡献而发散，因此这种情形不能被认为是畴壁上场局域化的现实机制.
英文摘要：
In this paper a model describing fermions and gauge field localized on a domain wall is considered. The zero-mode sector of the model reproduces four-dimensional spinor electrodynamics. It is shown that in the resulting four-dimensional effective theory the lowest-order renormalized amplitude of the elastic $γγ$ scattering process is divergent due to the contributions of higher modes and thus such a scenario can not be considered as a realistic mechanism for fields localization on a domain wall.
