摘要:

在Randall-Sundrum膜世界方案中,研究了一个弦启发的3-形式引力模型.正如预期的那样,秩3反对称场被指数抑制。对于每个质量水平,质谱都大于Kalb-Ramond场的质谱。本文计算了三次型的无质量Kaluza-Klein模与声子的耦合,得到了三次型相互作用的耦合常数。这种耦合具有Tev $^{-1}$的量级,因此存在在Tev尺度上找到它的一些信号的可能性。

英文摘要:

A string-inspired 3-form-dilaton-gravity model is studied in a Randall-Sundrum brane world scenario. As expected, the rank-3 antisymmetric field is exponentially suppressed. For each mass level, the mass spectrum is bigger than the one for the Kalb-Ramond field. The coupling between the dilaton and the massless Kaluza-Klein mode of the 3-form is calculated and the coupling constant of the cubic interactions obtained numerically. This coupling are of the order of Tev$^{-1}$, therefore there exist a possibility to find some signal of it at Tev scale.
