Hi everyone. I have a doubt on charge conjugation symmetry. Consider the Standard Model lagrangian with just the gauge and the fermionic part (no Higgs and no Yukawa). This is invariant under [itex]SU(3)_C\times SU(2)_L\times SU(2)_R\times U(1)_Y[/itex]. Moreover, as any other field theory, it is [itex]CPT[/itex] invariant.(adsbygoogle = window.adsbygoogle || []).push({});

Since, however [itex]P[/itex] is clearly violated by the asymmetry in the left-right fields we know that [itex]CT[/itex] must be violated too.

What can we say about [itex]C[/itex] and [itex]T[/itex] independently?
