作为膜上场局域化机制的体原子自发对称性破缺

Spontaneous Symmetry Breaking in the Bulk as a Localization Mechanism of Fields on the Brane

Orfeu Bertolami, Carla Carvalho

摘要:

我们考虑实的和复杂的标量场的非最小耦合到大时空中的重力和研究他们的影响膜后获得一个非零的真空期望值。在考察复标量场的情况时,也考虑了最小耦合U(1)规范场,从而使自发对称性破缺发生。特别注意的是从结的条件,这对加强机制的自发对称性破缺的行为所产生的条款。我们发现,嵌入一个膜世界宇宙在一个大块时空赋予物质场可以诱导这种机制在非常高的能量,这意味着本地化的膜上的大块场。

英文摘要:

We consider real and complex scalar fields non-minimally coupled to gravity in the bulk spacetime and study their impact on the brane upon acquiring a non-vanishing vacuum expectation value. When examining the case of the complex scalar field, a minimally coupled U(1) gauge field is also considered so that spontaneous symmetry breaking can take place. Particular attention is paid to the terms arising from the junction conditions, which act towards reinforcing the mechanism of spontaneous symmetry breaking. We find that the embedding of a braneworld universe in a bulk spacetime endowed with matter fields can induce this mechanism at very high energies, which implies the localization on the brane of the bulk fields.
