Two times the difference of the negative log-likelihood (NLL) as a function of σ(pp →(q$^{light}$)H$^{\pm}$) B(H$^{\pm}$ → tb, t → blν) and σ(pp → bH$^{\pm}$)B(H$^{\pm}$ → tb, t → blν) with the best fit point extracted from the pDNN distribution for the $H^{\pm}$ mass $m_{H^{\pm}} = 600$ GeV. The solid and dashed contours represent the observed and expected limits, respectively. The points along the contours represent 68% and 95% CL regions, extracted from the 2∆NLL values of 2.30 and 5.99, respectively. The g2HDM predictions are also shown. The points along the g2HDM prediction line represent different $ρ_{tt}$, $ρ_{tc}$ coupling sets, with all other extra Yukawa couplings assumed to be zero.
