Renormalization of Quantum Gravity with Lagrange Multiplier Fields
F. T. Brandt, J. Frenkel, S. Martins-Filho +1
We study the renormalization of Einstein gravity coupled to a scalar field in the Lagrange multiplier (LM) formulation, where a pair of quantum LM fields, , is couple…
Supergravity with Lagrange Multiplier Fields in 2 + 1 Dimensions
D. G. C. McKeon, F. T. Brandt, J. Frenkel +1
We examine the first-order Einstein-Cartan (EC) action in 2+1 dimensions, including a cosmological term and its supersymmetric extension. In this setting the spin connection can be…
Equivalence of first and second order formulations of the Einstein-Hilbert theory
F. T. Brandt, J. Frenkel, S. Martins-Filho +1
We derive a general relation between the background effective actions, which directly proves that the two formulations of the Einstein-Hilbert theory with background fields are equ…
A Renormalizable Model of Quantized Gravitational and Matter Fields
D. G. C. McKeon, F. T. Brandt, J. Frenkel +1
A Lagrange multiplier field can be used to restrict radiative corrections to the Einstein-Hilbert action to one-loop order. This result is employed to show that it is possible to c…
Renormalization of the Einstein-Cartan Theory in First-Order Form
F. T. Brandt, J. Frenkel, S. Martins-Filho +1
We examine the Einstein-Cartan (EC) theory in first-order form, which has a diffeomorphism as well as a local Lorentz invariance. We study the renormalizability of this theory in t…
Field redefinition invariant Lagrange multiplier formalism with gauge symmetries
D. G. C. McKeon, F. T. Brandt, S. Martins-Filho
It has been shown that by using a Lagrange multiplier field to ensure that the classical equations of motion are satisfied, radiative effects beyond one-loop order are eliminated.…
On Restricting First Order Form of Gauge Theories to One-Loop Order
F. T. Brandt, J. Frenkel, S. Martins-Filho +1
The first order form of the Yang-Mills and Einstein-Hilbert actions are quantized, and it is shown how Green's functions computed using the first and the second order form of these…
First order formulation of the Yang-Mills theory in a background field
F. T. Brandt, J. Frenkel, D. G. C. McKeon
The background gauge renormalization of the first order formulation of the Yang-Mills theory is studied by using the BRST identities. Together with the background symmetry, these i…
Renormalization of six-dimensional Yang-Mills theory in a background gauge field
F. T. Brandt, J. Frenkel, D. G. C. McKeon
Using the background field method, we study in a general covariant gauge the renormalization of the 6-dimensional Yang-Mills theory. This requires background gauge invariant counte…
Structure of the Gluon Propagator at Finite Temperature
H. Arthur Weldon
The thermal self-energy of gluons generally depends on four Lorentz-invariant functions. Only two of these occur in the hard thermal loop approximation of Braaten and Pisarski beca…
