Searches for heavy Higgs bosons in the framework of 2HDM model

Abstract

The searches for heavy neutral and charged Higgs bosons are performed through the calculations of production cross sections using MadGraph5aMC@NLO program with ansatz of Yukawa coupling and the restricted parameter space connected with LHC Run 2 data. The searches for heavy resonances are performed in the framework of 2HDM model over the mass range 0.1 - 1 TeV for the $pp\rightarrow At\bar{b}$, $pp\rightarrow H^{+}b\bar{t}$ , $pp\rightarrow H^{+}t\bar{t}$ , $pp\rightarrow HHZ$ decay modes. The presented data demonstrate the jump in the production cross section of $H^{+} b\bar{t}$ and $HHZ$ production processes in the mass range of 100-200 GeV and 100-300 GeV accordingly at energy of 14 TeV.
