中文摘要：

在质心能量为14TeV的质子质子对撞机LHC上对RPV最小超对称模型下即共振态进行了探讨．在引入了frequentist likelihood ratio confidence level的统计方法后，在95％的置信度下，假设没有新物理的出现，对RPV耦合做出了比Tevatron实验更为精确的预期结果．

英文摘要：

The potential of searching sneutrino in high mass eμ final states in pp collisions at center-of-mass 14 TeV at LHC collider, in the framework of R-parity violating （RPV） supersymmetric model is investigated. By introducing a frequentist likelihood ratio confidence level statistical treatment, expected 95% C. L. direct limits on RPV couplings λ′311×λ312 for different sneutrino masses can be derived under the assumption of no evidence for new physics, which are more stringent than those measured at Tevatron experiments.
