论文摘要
具有几乎分层光希格斯诺诺斯的超对称模型在严格的限制下，从当前对蜘蛛的实验搜索进行了严格的限制，为自然问题提供了一致的解决方案。但是，由于难以检测的软性最终状态，在对撞机实验中探测压缩方案是一项挑战。为了克服这个问题，已经提出了策略，以利用大型强子对撞机的超递碰撞碰撞的光子融合，这对于安装在ATLAS和CMS探测器上的正向检测器的可行性是可行的。在本文中，我们在13 TEV LHC处通过Photon Fusion展示了Chargino对生产的搜索策略，实现了一种良好的灵敏度，可以排除$ M _ {\tildeχ^{\ pm} _ {1}} _ {1}}} $，最高270 GEV（308 GEV） $ΔM（\tildeχ^{\ pm} _ {1}，\tildeχ^{0} _ {1}）\ in [1,15] $ GEV，$ gev的集成亮度为100 fb $^{ - 1} $（3 ab $^$^$^{ - 1} $）at 95％c.l。
Supersymmetric models with nearly-degenerate light higgsinos provide a consistent solution to the naturalness problem under rigorous constraints from current experimental searches for sparticles. However, it is challenging to probe the compressed scenarios at collider experiments due to the hard-to-detect soft final states. To overcome this issue, strategies have been proposed to take advantage of the photon fusion along the ultraperipheral collision at the Large Hadron Collider, which are feasible with the forward detectors installed at the ATLAS and CMS detectors. In this paper, we demonstrate a search strategy for the chargino pair production via photon fusion at the 13 TeV LHC, realizing a good sensitivity that can exclude $m_{\tildeχ^{\pm}_{1}}$ up to 270 GeV (308 GeV) for a mass splitting $Δm(\tildeχ^{\pm}_{1},\tildeχ^{0}_{1})\in[1,15]$ GeV with an integrated luminosity of 100 fb$^{-1}$ (3 ab$^{-1}$) at 95% C.L.
