论文摘要
在弱耦合的字符串理论中，分析了重晶型和深色勃雷光子与标准模型超负的混合。在包含SM校正后提供混合的直接混合以及有效的术语估计为最低顺序。将结果与有效的场理论（EFT）耦合进行比较，该耦合源自与SM相连的隐藏大N理论。与通用的EFT耦合相比，弦理论混合项通常是转向的。还分析了隐藏理论是全息理论的情况，也提供了抑制SM超负的混合术语。
The mixing of graviphotons and dark brane photons to the Standard Model hypercharge is analyzed in full generality, in weakly-coupled string theory. Both the direct mixing as well as effective terms that provide mixing after inclusion of SM corrections are estimated to lowest order. The results are compared with Effective Field Theory (EFT) couplings, originating in a hidden large-N theory coupled to the SM. The string theory mixing terms are typically subleading compared with the generic EFT couplings. The case where the hidden theory is a holographic theory is also analyzed, providing also suppressed mixing terms to the SM hypercharge.
