OPE's and the Dilaton Beta-Function for the 2-D N=1 Supersymmetric Non-Linear $σ$-Model

Using the superspace formalism, we compute for the two-dimensional N=1 supersymmetric non-linear $σ$-model, the order $(α^{\prime})^{2}$ $(R_{mnpq})^2$ (three-loop) correction to the central charge via the operator product expansion of the supercurrent with itself. The contribution vanishes, in agreement with previous results obtained from the usual $σ$-model $β$-function approach.

Prepotentials for (2,2) Supergravity

We present a complete solution of the constraints for two-dimensional, N=2 supergravity in N=2 superspace. We obtain explicit expressions for the covariant derivatives in terms of the vector superfield $H^m$ and, for the two versions of minimal (2,2) supergravity, a chiral or twisted chiral scalar superfield $ϕ$.
