The existence of one scalar doublet makes the existence of a second Higgs doublet probable. This study presents the search for this extra Higgs doublet, with CMS full 137 fb−1 Run II data with the cg → tH⁰/A⁰ → ttc/u process where H⁰ and A⁰ represent the extra scalar and pseudo-scalar of the second Higgs doublet in the generalized 2HDM model. The search covers Higgs mass values of 200-1000 GeV.
