General effective field theory of teleparallel gravity

Abstract: We construct the Effective Field Theory (EFT) of the teleparallel equivalent of general relativity (TEGR). Firstly, we present the necessary field redefinitions of the scalar field and the tetrads. Then we provide all the terms at next-to-leading-order, containing the torsion tensor and its derivatives, and derivatives of the scalar field, accompanied by generic scalar-field-dependent couplings, where all operators are suppressed by a scale Λ. Removing all redundant terms using the field redefinitions we result to the… Show more

“…Additionally, T (0) is used to represent the torsion scalar at the background level with the value T (0) = 6H 2 (not to be confused with the zero-th component of the contracted torsion tensor T 0 ). Hence the EFT action at leading order is found to be [49,53]…”

“…Furthermore, note that in the EFT approach f (T ) gravity can be regarded as a low-energy effective theory. It is possible that the strong coupling problem can be eliminated if other operators are introduced in the EFT action beyond the scale M [53].…”
