Let G be a compact connected Lie group, and (M, |) a compact Hamiltonian G-space, with moment map J : M Γ g\*. Under the assumption that these data are pre-quantizable, one can construct an associated Spin c Dirac operator % C , whose equivariant index yields a virtual representation of G. We prove
## Abstract I survey the recent construction of a family of new twistor string theories which are free from worldβsheet anomalies and give the spaceβtime spectra of Einstein supergravities, with second order field equations instead of the higher derivative conformal supergravities that arose from e
