Abstract

The notion of chirality for an electromagnetic field which is conserved in interactions with gravitons is formulated. The corresponding chiral current is the one-particle-state analouge of the Pauli-Lubansky vector. The anomaly of this current in an external gravitational field is found. The results obtained are used for the calculation of the electromagnetic radiative correction to the fermionic chiral anomaly in a gravitational field.
