论文摘要
通过采用出生的电磁构想的想法，Weitzenböck时空的出生式行李决定重力提供了一种在古典层面平滑大爆炸奇点的方法。我们考虑了该重力较高维度的较高效率延伸中的较厚的Braneworld方案，并研究了对棕褐色结构和重力扰动的扭转影响。对于三个特定的参数选择，可以获得分析域壁溶液。它们具有相似的勃雷构型，随着时空扭转的强度，勃雷厚度变得更薄。对于每个模型，无质量的吸引力位于棕褐色，随着时空扭转的增强，定位的宽度降低，而大量的吸引力在大量中繁殖，并与$ {1}/{（K r）^{3}} $成比例的校正项贡献了校正项。从重力实验估算了基本的5维重力量表上的稀疏性约束。此外，分析了kaluza-klein graviton的参数范围。
By adopting the idea of Born-Infeld electromagnetism, the Born-Infeld determinantal gravity in Weitzenböck spacetime provides a way to smooth the Big Bang singularity at the classical level. We consider a thick braneworld scenario in the higher-dimensional extension of this gravity, and investigate the torsion effects on the brane structure and gravitational perturbation. For three particular parameter choices, analytic domain wall solutions are obtained. They have a similar brane configuration that the brane thickness becomes thinner as the spacetime torsion gets stronger. For each model, the massless graviton is localized on the brane with the width of localization decreasing with the enhancement of the spacetime torsion, while the massive gravitons propagate in the bulk and contribute a correction term proportional to ${1}/{(k r)^{3}}$ to the Newtonian potential. A sparsity constraint on the fundamental 5-dimensional gravitational scale is estimated from the gravitational experiment. Moreover, the parameter ranges in which the Kaluza-Klein gravitons are tachyonic free are analyzed.
