| 英文摘要 | A search is presented for long-lived particles with a mass between 25 and 50 gev/c(2) and a lifetime between 2 and 500 ps, using proton-proton collision data corresponding to an integrated luminosity of 2.0 fb(-1), collected by the lhcb detector at centre-of-mass energies of 7 and 8 tev. the particles are assumed to be pair-produced in the decay of a 125 gev/c(2) standard-model-like higgs boson. the experimental signature is a single long-lived particle, identified by a displaced vertex with two associated jets. no excess above background is observed and limits are set on the production cross-section as a function of the mass and lifetime of the long-lived particle. |
