Theoretical analysis characterizes the BRST cohomology spaces in the Chapline-Manton model, suggesting new constraints on consistent gauge field interactions.
Key Points
To determine the local BRST cohomology and classify gauge-invariant structures within the Chapline-Manton model.
Applied algebraic descent equations and homological perturbation methods to coupled gauge and supergravity fields.
Evaluated the ghost-number grading and field antibracket relations within the Batalin-Vilkovisky framework.
Identified all non-trivial local cohomology classes corresponding to invariant field equations and candidate anomalies.
Demonstrated that non-trivial deformations are tightly constrained by the underlying supersymmetric Chern-Simons coupling.
