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.12 p.application/pdfengcc-by (c) Garrido Beltrán, Lluís et al., 2015http://creativecommons.org/licenses/by/3.0/esBosons de HiggsFísica de partículesExperimentsHiggs bosonsParticle physicsExperimentsinfo:eu-repo/semantics/article6536912020-05-06info:eu-repo/semantics/openAccess25983649
