标题： Bulk fields with general brane kinetic terms

摘要： 我们分析了额外维理论中（具有或不具有超对称性），体标量、费米子和规范玻色子的广义膜动能项的影响。 特别是，当这些项包含与膜正交的导数时，我们发现了奇异的行为。 这种行为是由二阶及更高阶微扰论中的$\delta(0)$发散引起的。 我们论证了这种行为可以通过经典重整化来平滑处理。 显示英文摘要

摘要： We analyse the effect of general brane kinetic terms for bulk scalars, fermions and gauge bosons in theories with extra dimensions, with and without supersymmetry. We find in particular a singular behaviour when these terms contain derivatives orthogonal to the brane. This is brought about by $\delta(0)$ divergences arising at second and higher order in perturbation theory. We argue that this behaviour can be smoothed down by classical renormalization.
