Search for a charged Higgs boson decaying to charm and bottom quarks in proton-proton collisions at √s=8 TeV

A search for charged Higgs boson decaying to a charm and a bottom quark (H+ → cb) is performed using 19.7 fb−1 of pp collision data at √ s = 8 TeV. The production mechanism investigated in this search is tt pair production in which one top quark decays to a charged Higgs boson and a bottom quark...
