膜世界场景中的扭转效应

Torsion Effects in Braneworld Scenarios

J. M. Hoff da Silva, R. da Rocha

摘要:

我们提出了在体和膜上都具有扭转项的膜世界模型的引力方面。为了研究真正由体扭转项引起的可想象且可测量的引力效应,我们分析了扭转存在时黑洞区域的变化。此外,我们推广了著名的结果一致性条件的框架,包括膜挠项。它示出,在一个粗略的估计,所产生的影响一般被抑制的内部空间体积。这种形式主义提供了可管理的模型及其在此背景下对重力某些方面的可能影响,以及可认知的校正和物理效应。

英文摘要:

We present gravitational aspects of braneworld models endowed with torsion terms both in the bulk and on the brane. In order to investigate a conceivable and measurable gravitational effect, arising genuinely from bulk torsion terms, we analyze the variation in the black hole area by the presence of torsion. Furthermore, we extend the well known results about consistency conditions in a framework that incorporates brane torsion terms. It is shown, in a rough estimate, that the resulting effects are generally suppressed by the internal space volume. This formalism provides manageable models and their possible ramifications into some aspects of gravity in this context, and cognizable corrections and physical effects as well.
