Search for long-lived neutral particles in pp collisions at root s = 13 TeV that decay into displaced hadronic jets in the ATLAS calorimeter Aaboud, M. Aguilar Saavedra, Juan Antonio Atlas Collaboration This paper describes a search for pairs of neutral, long-lived particles decaying in the ATLAS calorimeter. Long-lived particles occur in many extensions to the Standard Model and may elude searches for new promptly decaying particles. The analysis considers neutral, long-lived scalars with masses between 5 and 400 GeV, produced from decays of heavy bosons with masses between 125 and 1000 GeV, where the long-lived scalars decay into StandardModel fermions. The analysis uses either 10.8 fb−1 or 33.0 fb−1 of data (depending on the trigger) recorded in 2016 at the LHC with the ATLAS detector in proton–proton collisions at a centre-of-mass energy of 13 TeV. No significant excess is observed, and limits are reported on the production cross section times branching ratio as a function of the proper decay length of the long-lived particles. 2019-10-24T09:43:37Z 2019-10-24T09:43:37Z 2019-06-07 info:eu-repo/semantics/article Aaboud, M.
