title = "Deformed covariance in spherically symmetric vacuum models of loop quantum gravity: Consistency in Euclidean and self-dual gravity",
abstract = "Different versions of consistent canonical realizations of hypersurface deformations of spherically symmetric spacetimes have been derived in models of loop quantum gravity, modifying the classical dynamics and sometimes also the structure of spacetime. Based on a canonical version of effective field theory, this paper provides a unified treatment, showing that modified spacetime structures are generic in this setting. The special case of Euclidean gravity demonstrates agreement also with existing operator calculations.",
