Search for Stable Massive Particles with the ATLAS detector in proton--proton collisions at $\mathbf{\sqrt{s}=13}$ TeV

A search for heavy long-lived charged $R$-hadrons is performed using data from proton--proton collisions at $\sqrt{s}=13$ TeV collected by the ATLAS Experiment at the Large Hadron Collider at CERN. The analysis utilises both time-of-flight and specific-ionisation energy-loss measurements to derive the velocity and subsequently the mass of the particles and places upper cross-section limits in a mass range from 600 GeV to 2000 GeV as well as mass exclusion limits for stable $R$-hadrons.
