On the geometric quantization and BRST quantization for bosonic strings

Physics Letters B, 1989
Abstract The complex geometry and the geometric quantization for bosonic strings are discussed. It is found that the conformal anomalies in the holomorphic and anti-holomorphic Fock spaces may be interpreted as curvatures of the holomorphic and anti-holomorphic Fock bundles on G″ = G/H.

Local operator algebras of charged states in gauge theory and gravity

Journal of High Energy Physics
Powerful techniques have been developed in quantum field theory that employ algebras of local operators, yet local operators cannot create physical charged states in gauge theory or physical nonzero-energy states in perturbative quantum gravity. A common

Anomalous BRST quantization

Nuclear Physics B, 1987
Abstract A quantum gauge theory is anomalous within the BRST quantization if there does not exist any conserved, nilpotent BRST charge. What is to be called the BRST charge is then either a nilpotent of a conserved charge. It is proposed that a particular conserved charge may be used to consistently quantize an anomalous gauge theory.

Pair production of massive charged vector bosons from the worldline

Journal of High Energy Physics
We investigate a worldline formulation for a massive spin-1 particle interacting with an electromagnetic background. Two first-quantized descriptions of the spin degrees of freedom are considered: one based on bosonic oscillators and the other on ...

Soliton quantization in the BRST scheme

Physics Letters B, 1992
Abstract We apply the BRST quantization method to nonlinear field theories admitting solitonic solutions. We explicitly evaluate the quantum corrections to the soliton masses and transition amplitudes of the field operator. We compare our results with those obtained with more conventional methods.

Crossed products, conditional expectations and constraint quantization

Nuclear Physics B
Recent work has highlighted the importance of crossed products in correctly elucidating the operator algebraic approach to quantum field theories. In the gravitational context, the crossed product simultaneously promotes von Neumann algebras associated ...

Classical statistical simulation of quantum field theory

Journal of High Energy Physics
We propose a procedure of computing the n-point function in perturbation theory of the quantum field theory as the average over the complex Gaussian noises in a classical theory.

Gauge Symmetry Beyond Perturbation Theory: BRST and Anti-BRST Structure, Background Fields, and Infrared Dynamics of Yang–Mills Theory

Particles
We present a pedagogical and self-contained account of the functional formulation of non-Abelian gauge theories, aimed at the construction of a process-independent effective charge for Yang–Mills theory.
