With respect to the original review article [1], the corrected couplings of the Higgs doublets ${\Phi }_1$ and ${\Phi }_2$ in the 2HDM type-I, type-II, lepton-specific and flipped scenarios are shown in

Table 1. Coupling coefficients of the neutral bosons h, H and A to fermions (top) and vector bosons (bottom). By convention, the Yukawa couplings are the same for up-type quarks (u) and may differ for down-type quarks (d) and charged leptons (ℓ) depending on the 2HDM type for models with built-in flavour conservation. These coefficients $\xi$ are defined such that the Yukawa Lagrangian terms are $-(m_f/v)\overline{f}f\varphi$ and $i(m_f/v)\overline{f}{\gamma }_{5}fA$, where $f=u,d,\ell$ and $\varphi =h,H$. The coupling coefficients to vector bosons are defined such that the Feynman rule for the coupling $\varphi VV$ is given by $2i{m}_V^2\xi (\varphi ,VV)g_{\mu \nu }/v$, where $\varphi$ = h, H, A and V = W, Z. The notations $s_{\beta -\alpha }$, $c_{\beta -\alpha }$ and $t_{\beta }$ refer to $sin(\beta -\alpha )$, $cos(\beta -\alpha )$ and $tan\beta$, respectively.
