Search for new Higgs bosons via same-sign top quark pair production in association with a jet in proton-proton collisions at s = 13 TeV

A search is presented for new Higgs bosons in proton-proton (pp) collision events in which a same-sign top quark pair is produced in association with a jet, via the p p → t H / A → t t c ‾ and p p → t H / A → t t u ‾ processes. Here, H and A represent the extra scalar and pseudoscalar boson, respect
