A note on the relation between different forms of superparticle dynamics

Artikel i vetenskaplig tidskrift, 1993

A formulation of D=10 superparticle dynamics is given that contain space-time and twistor variables. The set of constraints is entirely first class, and gauge conditions may be imposed that reduces the system to a Casalbuoni-Brink-Schwarz superparticle, a spinning particle or a twistor particle.
