论文摘要
右撇子中微子（$ν_{r} $）通常被视为新隐藏物理的门户。考虑一个符号单元标量$（ϕ）$，它通过$ν_{r}ν_=ν_{r} ϕ $ term to tange singlet标量$（ϕ）$。这样的$ν_{r} $ - Philic标量不会在树级上与带电的费米子进行互动，但是循环引起的有效互动是不可避免的，这在这项工作中是系统地研究的。环路诱导的耦合的大小偶然地符合第五强搜索的当前灵敏度。特别是，在最近对中子星星合并的LIGO观察结果中，可以测试环路诱导的耦合，因为在由$ν_{r} $ - Philic scalcor介导的二进制系统中可能有相当大的Yukawa力。
Right-handed neutrinos ($ν_{R}$) are often considered as a portal to new hidden physics. It is tempting to consider a gauge singlet scalar $(ϕ)$ that exclusively couples to $ν_{R}$ via a $ν_{R}ν_{R}ϕ$ term. Such a $ν_{R}$-philic scalar does not interact with charged fermions at tree level but loop-induced effective interactions are inevitable, which are systematically investigated in this work. The magnitude of the loop-induced couplings coincidentally meets the current sensitivity of fifth-force searches. In particular, the loop-induced coupling to muons could be tested in the recent LIGO observations of neutron star mergers as there might be a sizable Yukawa force in the binary system mediated by the $ν_{R}$-philic scalar.
