我们提出了一个搜索策略，使用大型强子对撞机作为光子对撞机开放的敏感性标量轻子（slepton轻子）的生产与质量约15至60 GeV以上的中性伴子暗物质的χ 10。这一地区有丰富的遗迹和μ介子。然而，传统的搜索是由不可约的diboson背景阻碍。我们克服了这个障碍，测量初始状态的运动学和丢失的动量四矢量质子标记的超周边碰撞使用前向探测器。在13 TeV的质子碰撞中，我们证明了在15 <$Δm（π π，χ π 10）<$60 GeV的能量下，对质量高达200 GeV的slepton的灵敏度超过LEP。我们鼓励LHC合作，为发现新物理开辟这一前沿领域。
We propose a search strategy using the LHC as a photon collider to open sensitivity to scalar lepton (slepton ℓ˜) production with masses around 15 to 60 GeV above that of neutralino dark matter χ˜10. This region is favored by relic abundance and muonarguments. However, conventional searches are hindered by the irreducible diboson background. We overcome this obstruction by measuring initial state kinematics and the missing momentum four-vector in proton-tagged ultraperipheral collisions using forward detectors. We demonstrate sensitivity beyond LEP for slepton masses of up to 200 GeV for 15≲Δm(ℓ˜,χ˜10)≲60 GeV withof 13 TeV proton collisions. We encourage the LHC collaborations to open this forward frontier for discovering new physics.
