摘要：

构造了动态局域在畴壁膜上的3+1维有效场的SU（5）大统一格式。这是通过汇合的对称性冲突机制对称性突破通过域壁形成，和Dvali-Shifman规范玻色子本地化的想法。它需要E_6规范不变作用量，得到的畴壁解在畴壁两侧的两个体区域中E_6破缺为不同嵌入的SO（10）× U（1）子群。在壁面上，不破缺对称是两个体子群的交集，包含SU（5）。E_6的27中的4+1维费米子族在SU（5）的5^* + 10 + 1 + 1表示中产生定域左手零模。剩下的10个费米子分量的27个是离域奇异状态，没有出现在有效的3+1维理论的畴壁膜。该方案是兼容的2型兰德尔-Sundrum机制的引力子局域化的单一额外的维度是无限的。

英文摘要：

An SU(5) grand unification scheme for effective 3+1-dimensional fields dynamically localised on a domain-wall brane is constructed. This is achieved through the confluence of the clash-of-symmetries mechanism for symmetry breaking through domain-wall formation, and the Dvali-Shifman gauge-boson localisation idea. It requires an E_6 gauge-invariant action, yielding a domain-wall solution that has E_6 broken to differently embedded SO(10) x U(1) subgroups in the two bulk regions on opposite sides of the wall. On the wall itself, the unbroken symmetry is the intersection of the two bulk subgroups, and contains SU(5). A 4+1-dimensional fermion family in the 27 of E_6 gives rise to localised left-handed zero-modes in the 5^* + 10 + 1 + 1 representation of SU(5). The remaining ten fermion components of the 27 are delocalised exotic states, not appearing in the effective 3+1-dimensional theory on the domain-wall brane. The scheme is compatible with the type-2 Randall-Sundrum mechanism for graviton localisation; the single extra dimension is infinite.
