我考虑在光滑(有限厚度)孤子上产生的引力。引力子动力学项与体标量耦合，得到孤子真空期望值。Kaluza-Klein模与孤子局域物质的耦合被抑制，产生了4D和5D行为的交叉距离$rc=Mp^2/M*^3$。该系统可以看作是Dvali、Gabadadze和Porrati模型的有限厚度膜正则化。
I consider gravity induced over a smooth (finite thickness) soliton. Graviton kinetic term is coupled to bulk scalar that develops solitonic vacuum expectation value. Couplings of Kaluza-Klein modes to soliton-localized matter are suppressed, giving rise to crossover distance $r_c=M_{P}^2/M_{*}^3$ between 4D and 5D behavior. This system can be viewed as a finite thickness brane regularization of the model of Dvali, Gabadadze and Porrati.
