首次搜索超对称性的矢量玻色子融合拓扑。搜索的目标是至少有两个轻子的最终状态，大的横向动量丢失，以及两个快速分离的喷流。该数据样本对应于在CERN LHC的CMS探测器收集的19.7 fb − 1的质子-质子碰撞的积分光度，其能量为8 TeV。所观察到的dijet不变质谱被发现与预期的标准模型预测是一致的。假设τ轻子的超对称伴子是最轻的slepton，最轻的slepton比charginos轻，则在有两个相关喷流的情况下，对电荷伴子和中性伴子的产生截面设定了上限。对于所谓的压缩质谱场景，其中最轻的超对称粒子（cid：101）X 01与下一个最轻的质量简并的高更诺粒子（cid：101）X 02和（cid：101）X ± 1之间的质量差为50 GeV，为后两种粒子设置170 GeV的质量下限。
The first search for supersymmetry in the vector-boson fusion topology is presented. The search targets final states with at least two leptons, large missing transverse momentum, and two jets with a large separation in rapidity. The data sample corresponds to an integrated luminosity of 19.7 fb − 1 of proton-proton collisions at √ s = 8 TeV collected with the CMS detector at the CERN LHC. The observed dijet invariant mass spectrum is found to be consistent with the expected standard model prediction. Upper limits are set on the cross sections for chargino and neutralino production with two associated jets, assuming the supersymmetric partner of the τ lepton to be the lightest slepton and the lightest slepton to be lighter than the charginos. For a so-called compressed-mass-spectrum scenario in which the mass difference between the lightest supersymmetric particle (cid:101) χ 01 and the next lightest, mass-degenerate, gaugino particles (cid:101) χ 02 and (cid:101) χ ± 1 is 50 GeV, a mass lower limit of 170 GeV is set for these latter two particles.
