Search for heavy particles decaying into top-quark pairs using lepton-plus-jets events in proton–proton collisions at s=13 TeV with the ATLAS detector

A search for new heavy particles that decay into top-quark pairs is performed using data collected from proton–proton collisions at a centre-of-mass energy of 13 TeV$$\text {TeV}$$ by the ATLAS detector at the Large Hadron Collider. The integrated luminosity of the data sample is 36.1 fb-1
