我们研究了五维费米子局域化的膜，我们描述的域壁，当两个平行的膜碰撞在一个五维闵可夫斯基背景时空的行为。我们发现，即使在碰撞之后，大多数费米子仍然作为一个整体被定位在两个膜上。然而，有多少费米子局域在哪一个膜上敏感地依赖于入射速度和耦合常数，除非费米子同时存在于两个膜上。
We study the behaviour of five-dimensional fermions localized on branes, which we describe by domain walls, when two parallel branes collide in a five-dimensional Minkowski background spacetime. We find that most fermions are localized on both branes as a whole even after collision. However, how much fermions are localized on which brane depends sensitively on the incident velocity and the coupling constants unless the fermions exist on both branes.
