Searches for displaced jets and long-lived particles with ATLAS

The production of heavy long-lived particles in pp collisions at LHC has been searched for with the ATLAS detector, exploiting experimental signatures such as vertices displaced from the pp interaction point, slow charged particles traversing the detector, and energy deposits delayed with respect to the pp interaction time. As no evidence for any excess above expected backgrounds has been found, new constraints on models of new physics have been set in the framework of gauge-mediated supersymmetry breaking models and of R-parity violating supersymmetry.
