We have performed a search for gluinos (g) and scalar quarks (q) in a data sample of 84 pb(-1) of pp collisions at square root[s] = 1.8 TeV, recorded by the Collider Detector at Fermilab. We investigate the final state of large missing transverse energy and three or more jets, a characteristic signature in R-parity-conserving supersymmetric models. The analysis has been performed "blind," in that the inspection of the signal region is made only after the predictions from standard model backgrounds have been calculated. Comparing the data with predictions of constrained supersymmetric models, we exclude gluino masses below 195 GeV/c2 (95% C.L.), independent of the squark mass. For the case m(q) approximately m(g), gluino masses below 300 GeV/c2 are excluded.
我们在费米实验室对撞机探测器记录的质心能量(\sqrt{s}=1.8) TeV的质子-质子碰撞的84 pb(^{-1})数据样本中，对胶微子（(\tilde{g})）和标量夸克（(\tilde{q})）进行了搜索。我们研究了大的横向缺失能量和三个或更多喷注的末态，这是R宇称守恒超对称模型中的一个特征信号。该分析是在“盲态”下进行的，即仅在计算出标准模型背景的预测之后，才对信号区域进行检查。将数据与受限超对称模型的预测进行比较，我们排除了低于195 GeV/c(^{2})（95%置信水平）的胶微子质量，与夸克质量无关。对于(m(\tilde{q})\approx m(\tilde{g}))的情况，排除了低于300 GeV/c(^{2})的胶微子质量。
