The particles are assumed to be pair-produced by the decay of a standard model-like Higgs boson. The experimental signature of the long-lived particle is a displaced vertex with two associated jets. No excess above the background is observed and limits are set on the production cross-section as a function of the long-lived particle mass and lifetime. %R 10.1140/epjc/s10052-015-3344-6 %U http://arxiv.org/abs/1412.3021 %U https://doi.org/10.1140/epjc/s10052-015-3344-6 %P 152 - 12pp
