No parity anomaly in massless QED3: a BPHZL approach
Oswaldo M. Del Cima, Daniel H. T. Franco, Olivier Piguet +1
In this letter we call into question the perturbatively parity breakdown at 1-loop for the massless QED_3 frequently claimed in the literature. As long as perturbative quantum fiel…
Plane Gravitational Radiation from Neutrinos Source with Kalb-Ramond Coupling
C. N. Ferreira, J. A. Helayel-Neto, N. A. Tomimura
In this work, we propose a model based on a non-minimal coupling of neutrinos to a Kalb-Ramond field. The latter is taken as a possible source for gravitational radiation. As an im…
Expository Remarks on Three-Dimensional Gravity and Hyperbolic Invariants
A. A. Bytsenko, M. E. X. Guimaraes
We consider complex invariants associated with compact real three-dimensional hyperbolic spaces. The contribution of the Chern-Simons invariants of irreducible U(n)-flat connection…
Truncated Heat Kernel and One-Loop Determinants for the BTZ Geometry
A. A. Bytsenko, M. E. X. Guimaraes
There is a special relation between the spectrum and the {\it truncated} heat kernel of the Euclidean BTZ black hole with the Patterson-Selberg zeta function. Using an orbifold des…
Partition Functions of Three-Dimensional Quantum Gravity and the Black Hole Entropy
A. A. Bytsenko, M. E. X. Guimaraes
We analyze aspects of the holographic principle relevant to the quantum gravity partition functions in Euclidean sector of AdS. The sum of the known contributions to the partit…
Center vortices as sources of Abelian dominance in pure SU(2) Yang-Mills theory
L. E. Oxman
We argue that in the infrared regime of continuum Yang-Mills theory, the possibility of a mass gap in the charged sector is closely associated with the center vortex sector. The an…
