Octonionic particles and the S7 symmetry

Artikel i vetenskaplig tidskrift, 1992

A manifestly Lorentz covariant quantization scheme for (super) particles in ten dimensions is given, using octonionic twistor variables, also applying to D=3, 4, and 6. The field-dependent gauge algebra for the twistor variables is (a superextension of) the seven-sphere. A BRS treatment of this symmetry is performed. Comments are made on conformal invariance and the topology of twistor space.
