A search is presented for new Higgs bosons, targeting proton-proton (pp) collision events with a same-sign top quark pair associated with an extra jet via the processes pp→ tH/A → ttc and pp→ tH/A → ttu, where H and A represent exotic scalar and pseudoscalar bosons, respectively. The study is based on data collected at a center-of-mass energy of 13 TeV with the CMS detector at LHC Run 2, corresponding to an integrated luminosity of 138 fb-1. The analysis is made based on generalized two-Higgs-doublet model (g2HDM). It targets the new Higgs masses ranging from 200 GeV to 1TeV and extra Yukawa couplings, ρtu and ρtc, from 0.1 to 1.0. Two scenarios are studied, in which only one of H and A exists or in which they coexist and interfere. No significant excess above standard model predictions is observed.
