  • Pauli-Lubanski, supertwistors, and the superspinning particle 

    Arvanitakis, AS; Mezincescu, L; Townsend, Paul Kingsley (Springer NatureJournal of High Energy Physics, 2017-06-28)
    We present a novel construction of the super-Pauli-Lubanski pseudo-vector for 4D supersymmetry and show how it arises naturally from the spin-shell constraints in the supertwistor formulation of superparticle dynamics. We ...

  • Twistor description of spinning particles in AdS 

    Arvanitakis, AS; Barns-Graham, AE; Townsend, Paul Kingsley (Springer NatureJournal of High Energy Physics, 2018-01-01)
    The two-twistor formulation of particle mechanics in D-dimensional anti-de Sitter space for D=4,5,7, which linearises invariance under the AdS isometry group Sp(4;K) for K=R,C,H,, is generalized to the massless N-extended ...
