Search for light charged Higgs bosons decaying to charm and strange quarks in $ \mathrm{t} \overline{\mathrm{t}} $ events in proton-proton collisions at $ \sqrt{s}= $ 13 TeV
A search is presented for a light charged Higgs boson $ \mathrm{{H}^{\pm}} $ in top quark pair production ( $ \mathrm{t} \overline{\mathrm{t}} $), where one of the top quarks decays to an $ \mathrm{{H}^{\pm}} $ and a bottom quark, while the other decays to a $ \mathrm{W}^{\mp} $ boson and a bottom quark [...]
