In terms of gauge theory on natural bundles, gauge fields are linear connections on a world manifold \[X\], defined as principal connections on the linear frame bundle \[FX\], and a metric (tetrad) gravitational field plays the role of a Higgs field responsible for spontaneous symmetry breaking of general covariant transformations.[7]
this is to consider gravity and/or general relativity as a gauge theory
