论文摘要
大型强子电子对撞机（LHEC）已设计为使用质子束从高光度大量强度强调的强子对撞机的强烈电子束将深度非弹性散射的场推向高能量和强度边界。但是，LHEC还是新物理学的绝佳实验室。在这项工作中，我们建议搜索与Lepton的暗物质。这可能会产生$ ej $ +缺失的能量和$μj$ +缺失的能量信号，可以通过抑制标准模型背景的简单缺失能量削减来观察到。考虑到直接的暗物质检测和LHC约束，我们表明LHEC确实可以发现较弱的质量暗物质费米，最多350 GEV，这会重现正确的物质密度，并且对违反Lepton的风味具有有趣的含义。
The Large Hadron electron Collider (LHeC) has been designed to push the field of deep inelastic scattering to the high energy and intensity frontier using an intense electron beam with a proton beam from the High Luminosity-Large Hadron Collider. However, LHeC is also a great laboratory for new physics. In this work, we propose a search for dark matter that couples with leptons. This may yield $ej$+ missing energy and $μj$ + missing energy signals that can be potentially observed through simple missing-energy cuts that suppress the Standard Model background. Considering direct dark matter detection and LHC constraints, we show that LHeC can indeed discover a weak scale dark matter fermion for masses up to 350 GeV, which reproduces the correct relic density, and has interesting implications for lepton flavor violation.
