| Abstract: A search is presented for charged Higgs bosons ($ \text{H}^\pm $) in proton-proton ($ \text{pp} $) collision events via the $ \text{pp}\rightarrow $ (q) $ \text{H}^\pm $ processes with $ \text{H}^\pm\rightarrow\text{tb} $ decays. The analysis is based on the data collected at a center-of-mass energy of 13 TeV with the CMS detector at the LHC, corresponding to an integrated luminosity of 138 $ \text{fb}^{-1} $. Charged Higgs bosons in the 200 GeV to 1 TeV mass range are targeted in the search. The results are interpreted in the framework of the generalized two-Higgs-doublet model (g2HDM) assuming the real components of the extra Yukawa couplings $ \rho_{\text{tt}} $ and $ \rho_{\text{tc}} $ range up to unity. No significant excess above the standard model prediction is observed. Stringent upper limits at 95% confidence level are derived on the product of the cross section $ \sigma({\text{pp}\rightarrow $ (q) $ \text{H}^\pm}) $ and branching ratio $ \mathcal{B}({\text{H}^\pm\rightarrow\text{tb}}, {\text{t}\rightarrow \text{bl}\nu}) $, where $ \text{l}=$ e, $\mu $, for $ \text{H}^\pm $ boson masses up to $ m_{\text{H}^\pm}= $ 1 TeV for $ \rho_{\text{tc}} \gtrsim $ 0.15-0.5 depending on the $ m_{\text{H}^\pm} $ and $ \rho_{\text{tt}} $ assumption. The results represent the first search for charged Higgs bosons based on the g2HDM at any collider and complement the existing results on additional neutral Higgs bosons. | ||
