Adjusted Weil algebras for skeletal and loop models of the string Lie 2-algebra and their metric extensions yield local metric string structure connections whose gauge transformations close without fake flatness, matching and correcting gauged supergravity data.

abstract
We systematically study deformations of chiral forms with applications to string theory in mind. To first order in the coupling constant, this problem can be translated into the calculation of the local BRST cohomological group at ghost number zero. We completely solve this cohomology and present detailed proofs of results announced in a previous letter. In particular, we show that there is no room for non-abelian, local, deformations of a pure system of chiral p-forms.

Towards an M5-Brane Model II: Metric String Structures
Adjusted Weil algebras for skeletal and loop models of the string Lie 2-algebra and their metric extensions yield local metric string structure connections whose gauge transformations close without fake flatness, matching and correcting gauged supergravity data.
