Forward scattering amplitudes in the imaginary time formalism
F. T. Brandt, J. Frenkel, S. Martins-Filho +2
We study, in the imaginary time formalism, the relation between loops and on-shell forward scattering tree amplitudes in thermal field theories. This allows for an efficient evalua…

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…

Restricting loop expansions in gauge theories coupled to matter
F. T. Brandt, J. Frenkel, S. Martins-Filho +1
Quantizing any model in which a Lagrange multiplier (LM) field is used to restrict field configurations to those that satisfy the classical equations of motion, leads to at most on…
