C^(1/2)P^(1/2)T^(1/2) Symmetry of the Chaotic Inflation Dynamics

In this work is shown that standard dynamical equations of the chaotic inflation for a massive real scalar field hold an especial local gauge symmetry. Given symmetry admits that inflation field mass can be considered as an especial "charge". Also, it is shown that given equations except expected $CPT$ symmetry, hold surprisingly, $C^{{1/2}}P^{{1/2}}T^{{1/2}}$ symmetry too.
