With the help of harmonic gauge condition, graviton propagator can be
obtained by weak field expansion around the flat Minkowski metric
(assuming cosmological constant is zero).
Gravitation theory can also be written in the first order (Palatini)
formalism. In stead of the metric, the basic fields are vierbein e and
spin connection w. For weak field expansion around the flat space-time
(e = e0 = constant, w = 0), what are the propagators for vierbein and
spin connection respectively? Are there any references on the graviton
propagator in the first order formalism? Thanks!
