Two simple photon gauges in inflation
Original language description
Photon propagators for power-law inflation are constructed in two one-parameter families of noncovariant gauges, in an arbitrary number of spacetime dimensions. In both gauges photon propagators take relatively simple forms expressed in terms of scalar propagators and their derivatives. These are considerably simpler compared to their general covariant gauge counterpart. This makes feasible performing dimensionally regulated loop computations involving massless vector fields in inflation.
