Observed excluded phase-space regions, based on 95% CL limits, as a function of $m_{H^{\pm}}$ and $ρ_{tc}$ for various assumed $ρ_{tt}$ values represented with different colors. The limits are extracted from the pDNN distributions based on g2HDM assuming all the extra Yukawa couplings except $ρ_{tt}$ and $ρ_{tc}$ are zero. The results are obtained from the 95% CL limits on the cross section times branching fraction in Fig 6.
