  • A search is presented for long-lived particles with a mass between 25 and 50$$\,\mathrm{GeV}/c^{2}$$GeV/c2 and a lifetime between 2 and 500 ps, using proton–proton collision data corresponding to an integrated luminosity of 2.0$$\,\mathrm{fb}^{-1}$$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$$\,\mathrm{GeV}/c^{2}$$GeV/c2 Standard-Model-like Higgs boson. The experimental signature is a single… CONTINUE READING
