Superspace with manifest T-duality from type II superstring

Understand

A superspace formulation of type II superstring background with manifest T-duality symmetry is presented.

• This manifestly T-dual formulation is constructed in a space spanned by two sets of nondegenerate super-Poincare algebra.
• Supertorsion constraints are obtained from consistency of the kappa-symmetric Virasoro constraints.
• All superconnections and vielbein fields are solved in terms of a prepotential which is one of the vielbein components.
