Do Dibosons Dream of Semileptonic Sheep? Searching for heavy $Wh$ resonances and optimizing track reconstruction with the ATLAS detector / Vessella, Makayla
A search for new heavy vector resonances decaying into a $W$ boson and a Standard-Model Higgs boson ($h$), targeting a semileptonic final state where the $W$ boson decays into a lepton-neutrino pair and the Higgs boson decays into a b-quark pair, is performed using 139 fb$^{-1}$ of $\sqrt{s}$ = 13 T [...]
