具有体双曲子和挠率的Randall-Sundrum方案

A Randall-Sundrum scenario with bulk dilaton and torsion

Biswarup Mukhopadhyaya, Somasri Sen, Soumitra SenGupta

摘要:

我们考虑了一个字符串启发的torsion-dronon-gravity作用在Randall-Sundrum膜世界的情况下,并表明,在一个有效的四维理论的可见膜,秩2反对称Kalb-Ramond场(源的扭转)是指数抑制。这个结果与我们在[12]中的早期结果相似,在[12]中,在本体中不存在介子。这就解释了在我们的时空中,扭曲是看不见的。然而,在这种情况下,在Tev尺度的实验中,声子和挠率之间的三线性耦合~ Tev^{-1}可能会导致新的信号,带有额外扭曲维度的印记。

英文摘要:

We consider a string-inspired torsion-dilaton-gravity action in a Randall-Sundrum brane world scenario and show that, in an effective four-dimensional theory on the visible brane, the rank-2 antisymmetric Kalb-Ramond field (source of torsion) is exponentially suppressed. The result is similar to our earlier result in [12], where no dilaton was present in the bulk. This offers an explanation of the apparent invisibility of torsion in our space-time. However, in this case the trilinear couplings ~ Tev^{-1} between dilaton and torsion may lead to new signals in Tev scale experiments, bearing the stamp of extra warped dimensions.
