Title: Search for heavy long-lived charged R-hadrons with the ATLAS detector in 3.2 fb-1 of proton–proton collision data at s=13 TeV

A search for heavy long-lived charged R -hadrons is reported using a data sample corresponding to 3.2 fb -1 of proton–proton collisions at s=13 TeV collected by the ATLAS experiment at the Large Hadron Collider at CERN. The search is based on observables related to large ionisation losses and slow propagation velocities, which are signatures of heavy charged particles travelling significantly slower than the speed of light. No significant deviations from the expected background are observed. Lastly, upper limits at 95% confidence level are provided on the production cross section of long-lived R -hadrons in the mass range from 600 GeV to 2000 GeV and gluino, bottom and top squark masses are excluded up to 1580 GeV, 805 GeV and 890 GeV, respectively.
