| 英文摘要 | A search is presented formassive 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 8tev, corresponding to integrated luminosities of 1 and 2fb(-1), 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 80gev/c(2) and lifetimes from 5 to 100 ps 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/c(2) 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. |
