Search for a light charged Higgs boson in $t\to H^{\pm }b$ decays, with $H^{\pm }\to cb$, in the lepton+jets final state in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

ATLAS Collaboration

A search for a charged Higgs boson, $H^{\pm }$, produced in top-quark decays, $t\to H^{\pm }b$, is presented. The search targets $H^{\pm }$ decays into a bottom and a charm q…
