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

A search for heavy long-lived charged R-hadronsis reported using a data sample corresponding to 3.2fb-1 of proton–proton collisions at vs=13TeV 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. Upper limits at 95% confidence level are provided on the production cross section of long-lived R-hadronsin the mass range from 600 GeV to 2000 GeV and gluino, bottom and top squark masses are excluded up to 1580GeV, 805GeVand 890GeV, respectively.
