Manifestly covariant canonical quantization I: the free scalar field
Classical physics is reformulated as a constrained Hamiltonian system in the history phase space. Dynamics, i.e. the Euler-Lagrange equations, play the role of first-class constraints. This allows us to apply standard methods from the theory of constrained Hamiltonian systems, e.g. Dirac brackets and cohomological methods. In analogy with BRST quantization, we quantize in the history phase spac...
متن کاملManifestly covariant canonical quantization II: Gauge theory and anomalies
In hep-th/0411028 a new manifestly covariant canonical quantization method was developed. The idea is to quantize in the phase space of arbitrary histories first, and impose dynamics as first-class constraints afterwards. The Hamiltonian is defined covariantly as the generator of rigid translations of the fields relative to the observer. This formalism is now applied to theories with gauge symm...
متن کاملCovariant Quantization of the
By replacing ten-dimensional pure spinors with eleven-dimensional pure spinors, the formalism recently developed for covariantly quantizing the d=10 superparticle and super-string is extended to the d=11 superparticle and supermembrane. In this formalism, kappa symmetry is replaced by a BRST-like invariance using the nilpotent operator Q = λ α d α where d α is the worldvolume variable correspon...
متن کاملCovariant Quantization of Superstrings
L Introduction. The fermionic string has been proposed as a unified theory of matter interacting through gauge and gravitational forces. Attractive features of string theory include the rich massless particle spectrum containing a graviton, gauge vectors and chiral fermions spacetime supersymmetry, and most hkely finiteness as well. String theory is remarkably restricted. Internal consistency f...
متن کاملCovariant Quantization of the Superstring
After reviewing the Green-Schwarz superstring using the approach of Siegel, the su-perstring is covariantly quantized by constructing a BRST operator from the fermionic constraints and a bosonic pure spinor ghost variable. Physical massless vertex operators are constructed and, for the first time, N-point tree amplitudes are computed in a manifestly ten-dimensional super-Poincaré covariant mann...
