Twistors and the massive spinning particle
(IOP ScienceJournal of Physics A: Mathematical and Theoretical, 2015-12-07)Gauge-invariant twistor variables are found for the massive spinning particle with N-extended local worldline supersymmetry, in spacetime dimensions D = 3, 4, 6. The twistor action is manifestly Lorentz invariant but the ...

Worldline CPT and massless supermultiplets
(World Scientific PublishingInternational Journal of Modern Physics A, 2016-09-30)The action for a massless particle in 4D Minkowski space–time has a worldline-time reversing symmetry corresponding to CPT invariance of the quantum theory. The analogous symmetry of the $\mathscr{N}$-extended superparticle ...
