Description

This talk presents a search for long-lived particles with the ATLAS detector at the LHC based on the full Run 2 dataset. Such particles would move slower than the speed of light and can be identified using their high transverse momenta and large specific ionisation losses (dE/dx). Using the dE/dx measurement from the pixel detector layer provides sensitivity to particles with lifetimes down to approximately 1 ns with a mass ranging from 100 GeV up to 3 TeV. Interpretations for pair-production of long-lived R-hadrons, charginos and staus are presented, with sensitivity that significantly surpasses that of previous searches.
