扭曲膜世界模型

Aspects of warped braneworld models

Soumitra SenGupta

摘要:

我们回顾了与翘曲膜世界模型有关的各种关键问题,这些模型通过这些额外维度理论的有趣几何特征为我们提供了新的见解和物理现象的解释。本文从最初的Randall-Sundrum双膜模型出发,讨论了与这种膜世界有关的稳定性、层次性等重要问题。解释了体弹性模量稳定化中高阶导数项的作用。我们讨论了各种体场存在的意义,并展示了一个扭曲的膜世界模型如何解释我们膜上所有反对称体张量场的不可见性。我们还推广了多个弯曲维度的多重弯曲时空模型。结果表明,该模型可以解释标准模型费米子之间的质量等级以及费米子在具有一定手征的标准模型膜上的局域化现象。

英文摘要:

We review various key issues in connection with the warped braneworld models which provide us with new insights and explanations of physical phenomena through interesting geometrical features of such extra dimensional theories. Starting from the original Randall-Sundrum two brane models, we have discussed the stability, hierarchy and other important issues in connection with such braneworld. The role of higher derivative terms in the bulk for modulus stabilization has been explained. Implications of the existence of various bulk fields have been discussed and it has been shown how a warped braneworld model can explain the invisibility of all antisymmetric bulk tensor fields on our brane. We have also generalised the model for more than one warped dimensions in the form of a multiply warped spacetime. It is shown that such model can offer an explanation to the mass hierarchy among the standard model fermions and the localization of fermions on the standard model brane with a definite chirality.
