A Truly Crazy Idea About Type-IIB Supergravity and Heterotic Sigma-Models

We construct an explicit and manifestly (1,0) heterotic sigma-model where the background fields are those of 10D, N=IIB supergravity.Comment: 10 Pages, Latex (self contained macros

A Codicil To Massless Gauge Superfields of Higher Half-Odd Integer Superspins

We study theories of 4D, N=1 supersymmetric massless, arbitrary higher half odd-integer superspins. A new series of such theories is found to exist for arbitrary superspin Y (Y=s+1/2 for any integer s). The lowest member (s=1) of the series is the original off-shell formulation of 4D, N=1 supergravity first presented by Breitenlohner in 1977
