Search for a heavy charged Higgs boson decaying into a $W$ boson and a Higgs boson in final states with leptons and $b$-jets in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector

ATLAS Collaboration

This article presents a search for a heavy charged Higgs boson produced in association with a top quark and a bottom quark, and decaying into a $W$ boson and a $125$ GeV Higgs boso…
