Quantization of Einstein-Cartan theory in the first order form
F. T. Brandt, J. Frenkel, S. Martins-Filho +1
We consider the Einstein-Cartan theory with the tetrad and spin connection taken as being independent fields. Diffeomorphism invariance and local Lorentz invari…
Thermal gauge theories with Lagrange multiplier fields
F. T. Brandt, J. Frenkel, S. Martins-Filho +2
We study the Yang-Mills theory and quantum gravity at finite temperature, in the presence of Lagrange multiplier fields. These restrict the path integrals to field configurations w…
Use of Lagrange multiplier fields to eliminate multiloop corrections
F. T. Brandt, J. Frenkel, D. G. C. McKeon +1
The problem of eliminating divergences arising in quantum gravity is generally addressed by modifying the classical Einstein-Hilbert action. These modifications might involve the i…
Renormalization Scheme Ambiguities in the Models with More than One Coupling
D. G. C. McKeon, Chenguang Zhao
The process of renormalization to eliminate divergences arising in quantum field theory is not uniquely defined; one can always perform a finite renormalization, rendering finite p…
Multiple Couplings and Renormalization Scheme Ambiguities
D. G. C. McKeon, Chenguang Zhao
The ambiguities inherent in renormalization are considered when using mass-independent renormalization in massless theories that involve two coupling coupling constants. We review…
Renormalization Mass Scale and Scheme Dependence in the Perturbative Contribution to Inclusive Semileptonic Decays
F. A. Chishtie, D. G. C. McKeon, T. N. Sherry
We examine the perturbative calculation of the inclusive semi-leptonic decay rate for the -quark, using mass-independent renormalization. To finite order of perturbation the…
