Query: F-theory superspace backgrounds   F-theory is the theory proposed to incorporate superstring theory in a way
such that STU dualities are manifest. A useful description uses a current
superalgebra on a higher-dimensional worldvolume, following from an action for
a selfdual gauge field. Here the group "metric" appearing in the Schwinger
(central charge) term of this current superalgebra is generalized to a tensor,
in analogy to the usual generalization of the structure constants to the
torsion (and curvature). This allows introduction of a massless background
describing F-supergravity on the original bosonic worldvolume. The isotropy
group is represented on superspace, while the (exceptional) symmetry is
represented on the worldvolume. As an example, we solve off shell the
linearized superspace constraints of the massless sector of the F-theory that
generalizes the N=2 supergravity (+ matter) of 3D S(tring)-theory, the
corresponding manifestly T-dual theory of T-theory, and the N=1 supergravity of
4D M-theory. The results for the prepotential, its gauge transformation, and
action agree with those that were derived previously without reference to the
current algebra of the full F-theory.
