Pregeometry and euclidean quantum gravity

Einstein's general relativity can emerge from pregeometry, with the metric composed of more fundamental fields. We formulate euclidean pregeometry as a SO(4) - Yang-Mills theory. In addition to gauge fields we include vector field in representation group. The and diffeomorphism invariant kinetic terms for these permit well-defined functional integral, contrast gravity Einstein-Hilbert action. propagators all are well behaved at short distances, without tachyonic or ghost modes. long distance behavior is governed by composite corresponds relativity. particular, graviton propagator free poles despite presence higher order momentum expansion inverse propagator. This seems be valid candidate quantum gravity, obstructions analytic continuation Minkowski signature metric.
