Bulk-to-bulk photon propagator in AdS

Kostas Skenderis, Radu N. Moga

The photon bulk-to-bulk propagator in AdS is obtained in axial, Coulomb, and covariant gauges by solving equations for form factors after tensor decomposition.

Claims

C1strongest claim

We recover some previously existing results and obtain new expressions for the propagator in other gauges. The propagators obey the subsidiary conditions arising from gauge invariance, with BRST invariance implying a relation between the longitudinal components of the gauge field propagator and the ghost bulk-to-bulk propagator.

C2weakest assumption

That the chosen decomposition into independent tensor structures is complete and that the resulting system of equations for the form factors admits unique solutions consistent with the AdS geometry and the chosen gauge conditions without additional boundary or regularity assumptions.

C3one line summary

Derives photon bulk-to-bulk propagators in AdS in multiple gauges by tensor decomposition and form-factor solution, recovering prior results and adding new expressions with improved IR behavior in Fried-Yennie gauge.
