我们提出了一个暗扇形模型，再现了KOTO、MiniBooNE和μ子异常磁矩异常。暗区是由一个轻标量单线态S组成的，它与一个稍重的惰性中微子有很大的耦合，惰性中微子与活性中微子混合。标量通过汤川耦合与标准模型费米子耦合，通过高维耦合与光子耦合。KOTO信号是味道变化的企鹅过程KL → π 0 S，然后S衰变为中微子的结果。在MiniBooNE的中微子-核散射中产生的无菌中微子衰变为活性中微子和S，后者以电磁方式衰变并在低能量下产生事件过剩。
We present a dark sector model that reproduces the KOTO, MiniBooNE and muon anomalous magnetic moment anomalies. The dark sector is comprised of a light scalar singlet S that has a large coupling to a slightly heavier sterile neutrino that mixes with the active neutrinos. The scalar couples to standard model fermions via Yukawa couplings, and to photons via a higher-dimensional coupling. The KOTO signal is a result of the flavor-changing penguin process K L→ π 0 S followed by the decay of S to neutrinos. The sterile neutrino produced in neutrino-nucleus scattering at MiniBooNE decays to an active neutrino and S, which decays electromagnetically and creates an event excess at low energies.
