A Large-D Weyl Invariant String Model in Anti-de Sitter Space
Ian Davies, Paul Mansfield
TL;DR
This paper introduces a large-D Weyl invariant string model in Anti-de Sitter space, maintaining boundary Poincare symmetry through a specific ghost-matter coupling at leading order.
Contribution
It proposes a novel large-D string model in AdS space that is Weyl invariant, extending previous models by preserving boundary symmetries.
Findings
Weyl invariance achieved at leading order in large D
Boundary Poincare symmetry preserved
New ghost-matter coupling mechanism introduced
Abstract
Strings propagating in AdS_{D+1} are made Weyl invariant to leading order in large D by a ghost-matter coupling that preserves the Poincare symmetry of the boundary.
