# complex scalar field as a sum of scalar and pseudoscalar fields

Let's consider theory of a complex scalar field $$\phi = \frac{1}{\sqrt{2}}(s+\imath p)$$ Is it true that under CPT transformations $s$ is a scalar field and $p$ is a pseudoscalar field?

• Yes. CPT is an anti-linear anti-unitary operator. – Prahar Mar 9 '15 at 13:18
