Supersymmetry algebras in arbitrary signature and their R-symmetry groups

Understand

String theory, specifically type-II superstring theory, can be formulated in any ten-dimensional signature.

• To facilitate the study of supergravity and superstring theories in this setting, we present a uniform construction of supersymmetry algebras in arbitrary dimension and signature, which generalizes the ideas underlying symplectic Majorana spinors.
• In our formalism R-symmetry acts on an auxiliary multiplicity space which makes its action manifest.
• This allows us to provide extensive tables which list the R-symmetry groups of extended supersymmetry algebras for all signatures together with other useful information.
