... is

In principle, $A=A(\omega)$ and $B=B(\omega)$ , with $A+B=1$ . However, we shall demonstrate, later on, that $B=0$ , otherwise causality is violated. It follows that $A=1$ . Thus, it is legitimate to assume, for the moment, that $A$ and $B$ are independent of $\omega$ .

... convention.

Here, we are assuming that the laws of physics do not possess an intrinsic handedness. This is certainly the case for mechanics and electromagnetism. However, the weak interaction does possess an intrinsic handedness: that is, it is fundamentally different in a parity inverted universe. So, the equations governing the weak interaction do actually contain mixtures of tensors and pseudo-tensors.
