Weyl Covariance, and Proposals for Superconformal Prepotentials in 10D Superspaces (2007.05097v4)

Abstract: Proposals are made to describe the Weyl scaling transformation laws of supercovariant derivatives $\nabla{}{\underline A}$, the torsion supertensors $T{}{{\underline A} \, {\underline B}}{}^{{\underline C}}$, and curvature supertensors $R{}{{\underline A} \, {\underline B}}{}{\, \underline c} {}^{\underline d}$ in 10D superspaces. Starting from the proposal that an unconstrained supergravity prepotential for the 11D, $\mathcal{N}$ = 1 theory is described by a scalar superfield, considerations for supergravity prepotentials in the 10D theories are enumerated. We derive infinitesimal 10D superspace Weyl transformation laws and discover ten possible 10D, $\mathcal{N}$ = 1 superfield supergravity prepotentials. The first identification of all off-shell ten dimensional supergeometrical Weyl field strength tensors, constructed from respective torsions, is presented.
