Born-Infeld型引力理论中的宇宙弦解

Cosmic String Solution in a Born-Infeld Type Theory of Gravity

W. J. da Rocha, A. L. Naves de Oliveira, M. E. X. Guimaraes

摘要:

在这项工作中,我们得到了一个精确的解决方案的外部度规的本地宇宙弦的有效引力理论,所谓的NDL理论,这是在玻恩-因菲尔德理论的启发。解是由一组参数给出的,这组参数与广义相对论的参数有很大的不同。不同之处在于引力拉格朗日量的具体选择,它是基于引力理论的自旋1结构。

英文摘要:

In this work we derive an exact solution for the exterior metric of a local cosmic string in an effective theory of gravity, the so-called NDL theory, which is inspired in the Born-Infeld theory. The solution is given by a family of parameters which presents quite different features from that of the General Relativity theory. The differences come from the specific choice of the gravitation Lagrangian which is based on a spin-1 construction of the gravitation theory.
