论文摘要
我们在搜索光（$ 0.1-5 $ GEV）sgoldstinos中调查了FASER@LHC的观点，该型号具有低能（$ 10-10^4 $ tev）超对称性破坏的型号。我们认为侵略和风味违反了Sgoldstinos与标准型号费米子的耦合，并在Faser上找到可以测试的两个选项。即使是第一个FASER运行，也可以在模型参数空间中探测有趣的斑块，而第二次运行的Faser-II具有明显较大的检测器基准体积，可以彻底探索与LHC和CMS探测器探测的粒子物理的广泛超对称性扩展。
We investigate FASER@LHC perspectives in searches for light ($0.1-5$ GeV) sgoldstinos in models with low energy ($10-10^4$ TeV) supersymmetry breaking. We consider flavor conserving and flavor violating couplings of sgoldstinos to Standard Model fermions and find the both options to be testable at FASER. Even the first FASER run allows one to probe interesting patches in the model parameter space, while the second run, FASER-II, with significantly larger detector fiducial volume, gives a possibility to thoroughly explore a wide class of supersymmetric extensions of particle physics complementary to those probed at LHC with ATLAS and CMS detectors.
