Search for a light charged Higgs boson in $t\to H^{\pm }b$ decays, with $H^{\pm }\to cs$, in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

ATLAS Collaboration

A search for a light charged Higgs boson produced in decays of the top quark, $t\to H^{\pm }b$ with $H^{\pm }\to cs$, is presented. This search targets the production of top-quark pai…
