We present results of a search for R-parity-violating decay of the neutralino chi;01, taken as the lightest supersymmetric particle, to a muon and two jets. The decay proceeds through a lepton-number violating coupling lambda(')(2jk) (j=1,2; k=1,2,3), with R-parity conservation in all other production and decay processes. In the absence of candidate events from 77.5+/-3.9 pb(-1) of data collected by the D0 experiment at the Fermilab Tevatron in pp collisions at sqrt[s]=1.8 TeV, and with an expected background of 0.18+/-0.03+/-0.02 events, we set limits on squark and gluino masses within the framework of the minimal low-energy supergravity-supersymmetry model.
我们给出了对中性微子χ₀₁（被视为最轻的超对称粒子）衰变为一个μ子和两个喷注的R宇称破坏衰变的搜索结果。该衰变通过违反轻子数的耦合λ′(2jk)（j = 1,2；k = 1,2,3）进行，在所有其他产生和衰变过程中R宇称守恒。在费米实验室Tevatron的D0实验于√s = 1.8 TeV的质子-质子碰撞中收集的77.5±3.9 pb⁻¹数据中未发现候选事件，且预期本底为0.18±0.03±0.02个事件的情况下，我们在最小低能超引力-超对称模型框架内对 squark 和胶微子质量设置了限制。
