What is the graviton propagator in the first order formalism?

    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!
