Abstract
A search for $W^{\prime}$ production with decay to a top quark and a bottom quark in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector is presented. The hadronic decay of the top quark is identified using DNN-based boosted-object techniques. The dominant background is obtained by a data-driven method with small systematic uncertainties. The results are presented as upper limits on the $W^{\prime}$ production cross-section times the top-bottom channel branching ratio for several $W^{\prime}$ masses ranging from 1.5 to 5 TeV.
