We point out that vector boson fusion at the Large Hadron Collider (LHC) can lead to useful signals for charginos and neutralinos in supersymmetric scenarios where these particles are almost invisible. The proposed signals are just two forward jets with missing transverse energy. It is shown that, in this way, one can put by far the strongest constraint on the parameter space of a theory with anomaly mediated supersymmetry breaking at the LHC. In addition, scenarios where the lightest neutralinos and charginos are Higgsino-like can give signals of the above type.
我们指出，在大型强子对撞机（LHC）中，矢量玻色子融合可以在超对称情景下为带电超对称粒子和中性超对称粒子产生有用的信号，在这些情景中这些粒子几乎是不可见的。所提出的信号仅仅是两个具有横向缺失能量的前向喷注。结果表明，通过这种方式，人们可以在LHC上对具有反常介导超对称破缺的理论的参数空间施加迄今为止最强的限制。此外，最轻的中性超对称粒子和带电超对称粒子类希格斯玻色子的情景也可以给出上述类型的信号。
