Prospects for searches for heavy $Z^\prime$ and $W^\prime$ bosons in fermionic final states with the ATLAS experiment at the HL-LHC

This note presents the prospects for new heavy $W^\prime$ and $Z^\prime$ bosons at the high luminosity LHC with $3000$ fb$^{-1}$ of $\sqrt{s}~=~14$ TeV proton--proton collision data. These analyses are based on generator-level information with parameterised estimates applied to the final state particles to simulate the response of the upgraded ATLAS detector and pile-up collisions. $W^\prime$ bosons are searched for in final states with a bottom and a top quark or with a lepton plus missing transverse energy. Assuming a right-handed $W^\prime$ boson, $W^\prime$ masses up to 4.9 TeV can be excluded with the first search, while the second search excludes $W^\prime$ bosons predicted in the Sequential Standard Model for masses up to $7.9$ TeV in the lepton plus missing transverse energy final state. Results are presented for a search for $Z^\prime$ bosons in $t\bar{t}$ and dilepton final states. Masses below $6.5$ TeV for Sequential Standard Model $Z^\prime$ bosons can be excluded.
