Scalar-QED β-functions near Planck's Scale
Gentil O. Pires
The Renormalization Group Flow Equations of the Scalar-QED model near Planck's scale are computed within the framework of the average effective action. Exact Flow Equations, correc…
Some Quantum Aspects of Three-Dimensional Einstein-Chern-Simons-Proca Massive Gravity
Carlos Pinheiro, Gentil O. Pires, N. Tomimura
We present a 3-dimensional model for massive gravity with masses induced by topological (Chern-Simons) and Proca-like mass terms. Causality and unitarity are discussed at tree-leve…
On a Three-Dimensional Gravity Model with Higher Derivatives
Carlos Pinheiro, Gentil O. Pires, Claudio Sasaki
The purpose of this work is to present a model for 3D massive gravity with topological and higher-derivative terms. Causality and unitarity are discussed at tree-level. Power-count…
Some Quantum Aspects of D=3 Space-Time Massive Gravity
Carlos Pinheiro, Gentil O. Pires, Fernando A. B. Rabelo de Carvalho
We discuss some features of Einstein-Proca gravity in D=3 and 4 space-times. Our study includes a discussion on the tree-level unitarity and on the issue of light deflection in 3D…
1-Loop Analysis of the Photon Self-Energy due to 3D-Gravity
C. Pinheiro, G. O. Pires, F. A. B. Rabelo de Carvalho
A Maxwell-Chern-Simons field is minimally coupled to 3D-gravity. Feynman rules are written down and 1-loop corrections to the gauge-field self-energy are calculated. Transversality…
Extending the Barnes-Rivers Operators to D=3 Topological Gravity
C. Pinheiro, G. O. Pires
The spin-projector operators for symmetric rank-2 tensors are reassessed in connection with the issue of topologically massive gravity. The original proposal by Barnes and Rivers i…
