Updated search for long-lived particles decaying to jet pairs
A search is presented for long-lived particles with a mass between 25 and 50 GeV/c² 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 a...

| description | A search is presented for long-lived particles with a mass between 25 and 50 GeV/c² 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/c² 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. |
