Can a pseudoscalar with a mass of 365 GeV in two-Higgs-doublet models explain the CMS tt¯ excess?

Can a pseudoscalar with a mass of 365 GeV in two-Higgs-doublet models explain the CMS tt¯ excess?

We investigate the recently reported tt¯ excess by the CMS Collaboration within the framework of conventional Two-Higgs-Doublet Models (2HDMs). Considering all four types (I, II, X, and Y), we perform a comprehensive parameter space scan using the best-fit values for a pseudoscalar boson A: MA=365 G...
