For the <complex scalar fields>, use the conventional <particle> names: $\phi$ annihilates a light $\phi$ particle and creates a light <antiparticle> $\bar\phi$; $\Phi$ annihilates a heavy $\Phi$ particle and creates $\bar\Phi$. These choices make the distinction between <particle> labels and field symbols explicit throughout <2/c/ii> and <2/c/iii>. The couplings $g,h$ are real as required by the printed Hermitian <Lagrangian density>.
