论文摘要
我们检查了在与太阳中微子的新相互作用的背景下,在Xenon1t地下暗物质直接检测实验上观察到的最近报告的低能电子后坐力光谱。特别是我们表明,标量和矢量介质具有质量$ \ Lessim 50 $ kev耦合到瘦素的kev可能已经在Xenon1T实验中留下可见的签名,类似于观察到的峰值7 keV的峰值。这表明暗物质探测器已经与中微子散射实验(例如Gemma,Charm-II和Borexino)竞争。如果将Xenon1t的这些结果解释为这种物理学的新信号,那么适合天体物理学过多的面部挑战的参数似乎很难克服。如果他们被视为对新耦合的限制,那么他们将预示着一个新颖的精确探针的开始,除了带有暗物质探测器的标准模型之外。
We examine the recently-reported low-energy electron recoil spectrum observed at the XENON1T underground dark matter direct detection experiment, in the context of new interactions with solar neutrinos. In particular we show that scalar and vector mediators with masses $\lesssim 50$ keV coupled to leptons could already leave a visible signature in the XENON1T experiment, similar to the observed peak below 7 keV. This signals that dark matter detectors are already competing with neutrino scattering experiments such as GEMMA, CHARM-II and Borexino. If these results from XENON1T are interpreted as a new signal of such physics, the parameters which fit the excess face challenges from astrophysics which seem very difficult to overcome. If they are rather viewed as a constraint on new couplings, they herald the start of an era of novel precise probes of physics beyond the standard model with dark matter detectors.
