Double supergeometry

Year: 2016
Type: article
Abstract: A geometry of superspace corresponding to double field theory is developed, with type II supergravity in D = 10 as the main example. The formalism is based on an orthosymplectic extension OSp(d, d|2s) of the continuous T-duality group. Covariance under generalised super-diffeomorphisms is manifest. Ordinary superspace is obtained as a solution of the orthosymplectic section condition. A systematic study of curved superspace Bianchi identities is performed, and a relation to a double pure spinor superfield cohomology is established. A Ramond-Ramond superfield is constructed as an infinite-dimensional orthosymplectic spinor. Such objects in minimal orbits under the OSp supergroup (“pure spinors”) define super-sections.
