Several models beyond the Standard Model predict new particles which could have a significant lifetime owing to the mass-degeneracy, heavy intermediate particles or small coupling to the lighter particles. When such a long-lived particle decays far from a beam collision point, it is hard for standard event reconstruction targeting promptly decaying signals to detect it, in spite of the fact that a long-lived particle would leave a characteristic signature in the detector. To extend the sensitivity for such various BSM models, the ATLAS collaboration performs searches for long-lived particles using dedicated techniques to reconstruct the characteristic signatures. This paper reviews recently published results of searches for long-lived particles with displaced signatures using data collected by the ATLAS detector in 2015 and 2016 at the LHC.
