A search is presented for massive long-lived particles decaying into a muon and two quarks. The dataset consists of proton-proton interactions at centre-of-mass energies of 7 and 8 TeV, corresponding to integrated luminosities of 1 and 2[Formula: see text], respectively. The analysis is performed assuming a set of production mechanisms with simple topologies, including the production of a Higgs-like particle decaying into two long-lived particles. The mass range from 20 to 80 [Formula: see text] and lifetimes from 5 to 100[Formula: see text] are explored. Results are also interpreted in terms of neutralino production in different R-Parity violating supersymmetric models, with masses in the 23-198 GeV/[Formula: see text] range. No excess above the background expectation is observed and upper limits are set on the production cross-section for various points in the parameter space of theoretical models.
本文介绍了一项针对衰变为一个μ子和两个夸克的大质量长寿命粒子的搜索。数据集由质心能量为7和8 TeV的质子-质子相互作用组成，分别对应1和2[公式：见正文]的积分亮度。分析是在假设一组具有简单拓扑结构的产生机制下进行的，包括产生衰变为两个长寿命粒子的类希格斯粒子。探索了质量范围从20到80[公式：见正文]以及寿命从5到100[公式：见正文]的情况。结果也根据不同R宇称破坏超对称模型中的中性子产生进行了解释，其质量范围在23 - 198 GeV/[公式：见正文]之间。未观察到超出背景预期的过量信号，并对理论模型参数空间中各点的产生截面设定了上限。
