论文摘要
Xenon1t合作最近报告了能量范围内的电子后坐力事件过多的$ 1-7 \，\ mathrm {kev} $。如果中微子夫妇夫妇到具有强度$ g_ {νn} $的光矢量媒介的情况下，可以理解的是源自已知的太阳中微子通量，该中微子夫妇会与光子与强度$χ$和$ g_ {νn}χ\ um uc uc g_ {νn} $进行$ g_ {νn} $。在这里，我们表明，在远程矢量介导的中微子自我相互作用的可重新分解模型中，这种耦合值可以自然出现。该模型可以通过特征性的$ 1/t^2 $的能量依赖性来区分Xenon1t过量的其他解释。其他签名包括无形的希格斯和$ z $衰减和lepto-philic带电的希格斯，以$ 100 \，\ mathrm {gev} $。阿尔卑斯山II将探测可行参数空间的一部分。
The XENON1T collaboration recently reported an excess in electron recoil events in the energy range between $1-7\,\mathrm{keV}$. This excess could be understood to originate from the known solar neutrino flux, if neutrinos couple to a light vector-mediator with strength $g_{νN}$ that kinetically mixes with the photon with strength $χ$, and $g_{νN}χ\sim10^{-13}$. Here, we show that such coupling values can naturally arise in a renormalizable model of long-range vector-mediated neutrino self-interactions. The model could be discriminated from other explanations of the XENON1T excess by the characteristic $1/T^2$ energy dependence of the neutrino-electron scattering cross section. Other signatures include invisible Higgs and $Z$ decays and lepto-philic charged Higgses at a few $100\,\mathrm{GeV}$. ALPS II will probe part of the viable parameter space.
