as $\phi_2^\pm$ is effectively decoupled owing to its large mass. We will consider two scenarios for our analysis. One where the lightest charged Higgs consists almost entirely of the charged singlet field $\d^\pm$ and another where the lightest physical state is almost equal admixture of $\d^\pm$ and $H_L^\pm$. In Tab. \[tab:chig\] we provide four benchmark points for the lightest charged Higgs boson $H_1^\pm$, two for the minimal mixing and two for the maximal mixing scenarios respectively.

[C[1.5cm]{}|C[6.5cm]{}]{} Mass & Composition\
473.32 & $0.002 \phi_2^+ + 0.999 \d^+$\
1000.7 & $0.002 \phi_2^+ + 0.999 \d^+$\
432.58 & 0.03 ${\phi_1{^-}}^\ast-0.006 \phi_2^+ +0.72H_L^+ + 0.69 \d^+$\
1000.9 & 0.03 ${\phi_1{^-}}^\ast-0.006 \phi_2^+ +0.76H_L^+ + 0.65 \d^+$\

We also cross-check the corresponding scalar and pseudo-scalar neutral Higgs bosons for the set of parameters that we use to generate the above charged Higgs masses, given in Table. \[tab:chig\]. We ensure that the lightest scalar Higgs boson mass is 125 GeV and the pseudo-scalar sector has two massless Goldstone bosons, required to give masses to the $Z_R$ and $Z$ bosons.

The quark and lepton masses can be obtained from Eq. \[eq:yuk\] as: $$\begin{aligned}
M_{u} &=& Y^{q1} v_1+Y^{q2} v_2,~~M_d=Y^{q1} v_2+Y^{q2} v_1,~~M_l = Y^{l1} v_2+Y^{l2}v_1,~~M_\nu^D = Y^{l1} v_1+Y^{l2} v_2.\end{aligned}$$
