论文摘要
我们考虑了一个通用的深色光子，该光子是由隐藏的$ u（1）$量规对称性产生的，该对称是在右手中微子上施加的（$ν_{r} $）。这样的$ν_{r} $ - 由于缺乏正常物质的树级耦合，Philic Dark Photon自然是黑暗的。但是，如果$ν_{r} $通过DIRAC质量术语与左手中微子混合使用$ν_{r} $，则不可避免地与带电的Leptons和Quarks的循环诱导的耦合。我们研究了循环引起的耦合，并发现$ν_{r} $ - Philic Dark Photon并不是不可接受的黑暗，这对于未来在Ship，Faser，Faser，Belle-II，LHC 14 TEV等的深色光子搜索可能具有重要意义。
We consider a generic dark photon that arises from a hidden $U(1)$ gauge symmetry imposed on right-handed neutrinos ($ν_{R}$). Such a $ν_{R}$-philic dark photon is naturally dark due to the absence of tree-level couplings to normal matter. However, loop-induced couplings to charged leptons and quarks are inevitable, provided that $ν_{R}$ mix with left-handed neutrinos via Dirac mass terms. We investigate the loop-induced couplings and find that the $ν_{R}$-philic dark photon is not inaccessibly dark, which could be of potential importance to future dark photon searches at SHiP, FASER, Belle-II, LHC 14 TeV, etc.
