Production cross sections calculated for multiple decay modes

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.
