I think I got it. I'll go and read Peskin & Schröder to see if I missed anything. Thank you very much.

Oh, ok, my mistake. But still, isn't the accidental lepton number symmetry a little different? Consider the charged current term in the lagrangian: \mathcal{L}_e^{\textrm{CC}} \propto \overline{\nu_e}\,\gamma^\mu(1-\gamma_5)\,e\,W_\mu. Suppose we assign lepton number to the fields like so...

So, if I understood it correctly, one imposes CP invariance in the Standard Model lagrangian. The cubic term (H^3 after SSB) is a clear way of noticing that the desired CP invariance is only attained if the Higgs field itself is also CP invariant. As the_pulp, I am also familiar with the...

This may sound like a silly, trivial question... but why? How does one see that the parity of the SM Higgs is +1? On a sidenote, the SM Higgs charge conjugation number is also said to be +1. Again, how does one extract this from the theory? Thank you in advance for your attention.
