论文摘要
在这项工作中，我们研究了厚的brane中标量场的大量Kaluza-Klein（KK）模式的数值演变。我们在五个时空中得出klein-gordon方程，并获得进化方程和类似schrödinger的方程。标量KK模式作为初始数据的共鸣，标量场随着最大耗散边界条件的形式而发展。结果表明，有长寿命的标量KK共振粒子在棕褐色上，这表明这些共振可能被视为暗物质的候选者之一。
In this work, we investigate numerical evolution of massive Kaluza-Klein (KK) modes of a scalar field in a thick brane. We derive the Klein-Gordon equation in five dimensional spacetime, and obtain the evolution equation and the Schrödinger-like equation. With the resonances of the scalar KK modes as the initial data, the scalar field is evolved with the maximally dissipative boundary condition. The results show that there are scalar KK resonant particles with long life on the brane, which indicates that these resonances might be viewed as one of the candidates for dark matter.
