BRST Cohomology and Its Application to QED
نویسنده
چکیده
We construct the BRST cohomology under a positive-definite inner product and obtain the Hodge decomposition theorem at a non-degenerate state vector space V . The harmonic states isomorphic with a BRST cohomology class correspond to the physical Hilbert space with positive norm as long as the completeness of QBRST is satisfied. We explicitly define a “co-BRST” operator and analyze the quartet mechanism in QED. PACS numbers: 73.40.Hm, 73.20.Mf

Dual BRST Symmetry in QED
We discuss local and covariant dual BRST symmetry and its consequences in two-dimensional quantum electrodynamics (QED). With the help of BRSTand dual BRST charges, we explore the BRST cohomology of physical states in the quantum Hilbert space. The algebra between conserved and nilpotent BRSTand dual BRST charges leads to the existence of a BRST-extended Casimir operator. The Hodge decompositio...
متن کاملLie algebra cohomology and group structure of gauge theories
We explicitly construct the adjoint operator of coboundary operator and obtain the Hodge decomposition theorem and the Poincaré duality for the Lie algebra cohomology of the infinite-dimensional gauge transformation group. We show that the adjoint of the coboundary operator can be identified with the BRST adjoint generator Q for the Lie algebra cohomology induced by BRST generator Q. We also po...
متن کاملNew Local Symmetry for Qed
A new local, covariant and nilpotent symmetry is shown to exist for the interacting BRST invariant U(1) gauge theory in two dimensions of spacetime. Under this new symmetry , it is the gauge-fixing term that remains invariant and the corresponding transformations on the Dirac fields turn out to be the analogue of chiral transformations. Possible interpretation and implication of this symmetry a...
متن کاملDual Brst Symmetry for Qed
We show the existence of a co(dual)-BRST symmetry for the usual BRST invariant Lagrangian density of an Abelian gauge theory in two dimensions of space-time where a U(1) gauge field is coupled to the Noether conserved current (constructed by the Dirac fields). Under this new symmetry, it is the gauge-fixing term that remains invariant and the symmetry transformations on the Dirac fields are ana...
