Finite One-Loop Calculations in Quantum Gravity: Graviton Self-Energy, Perturbative Gauge Invariance and Slavnov–Ward Identities
نویسنده
چکیده
In this paper we show that the one-loop graviton self-energy contribution is ultraviolet finite, without introducing counterterms, and cutoff-free in the framework of causal perturbation theory. In addition, it satisfies the gravitational Slavnov–Ward identities for the two-point connected Green function. The condition of perturbative gauge invariance to second order for loop graphs is proved. Corrections to the Newtonian potential are also derived. PACS numbers: 0460, 1110

Scalar Matter Coupled to Quantum Gravity in the Causal Approach: Finite One-Loop Calculations and Perturbative Gauge Invariance
Quantum gravity coupled to scalar massive matter fields is investigated within the framework of causal perturbation theory. One-loop calculations include matter loop graviton self-energy and matter self-energy and yield ultraviolet finite and cutoff-free expressions. Perturbative gauge invariance to second order implies the usual Slavnov–Ward identities for the graviton self-energy in the loop ...
متن کاملFinite One-Loop Corrections and Perturbative Gauge Invariance in Quantum Gravity Coupled to Photon Fields
One-loop calculations in quantum gravity coupled to U(1)-Abelian fields (photon fields) are ultraviolet finite and cutoff-free in the framework of causal perturbation theory. We compute the photon loop correction to the graviton propagator and the photon self-energy in second order perturbation theory. Perturbative gauge invariance to second order is shown and generates the gravitational Slavno...
متن کاملGeneral structure of the graviton self-energy
The non-linear relation imposed by gauge invariance on the thermal self-energy of gluons, has been recently discussed by Weldon in an interesting paper [1]. He proved that in QCD, the Slavnov-Taylor identities [2,3] require a non-linear constraint among the structure functions which occur at finite temperature. In this brief report, we show that a similar behavior occurs in the gauge theory of ...
متن کاملThree-graviton vertex function in thermal quantum gravity.
The high temperature limit of the 3-graviton vertex function is studied in thermal quantum gravity, to one loop order. The leading (T ) contributions arising from internal gravitons are calculated and shown to be twice the ones associated with internal scalar particles, in correspondence with the two helicity states of the graviton. The gauge invariance of this result follows in consequence of ...
متن کاملHiggs Phenomenon for the Graviton in Ads Space
In this review, we summarize recent findings that show how standard 4-d Einstein gravity coupled to a conformal field theory can become massive in Anti de Sitter Space. Key ingredients in this phenomenon are non-standard “transparent” boundary condition given to the CFT fields and the fact that AdS space is not globally hyperbolic, due to the presence of a time-like boundary. 1 Ward Identities ...
