You want short notes of CPT Theorem so here is its shot notes:

In the context of classical mechanics and field theory continuous symmetry transformations and the associated conserved quantities were discussed. These continuous
symmetries were also analyzed in quantum field theory.
In contrast the CPT theorem is a statement about discrete symmetry transformations. It can be shown that under few assumptions a quantum field theory is symmetric with regard to the combination of the inversion of spatial coordinates (P), the inversion of charge (C) and the inversion of the direction of time (T).

Complete notes is given attached pdf file which you can free download whenever you want.
