The third way to 3D gravity
(World ScientificInternational Journal of Modern Physics D, 2015-10-09)
Consistency of Einstein’s gravitational field equation Gµν ∝ Tµν imposes a “conservation condition” on the T-tensor that is satisfied by (i) matter stress tensors, as a consequence of the matter equations of motion, and ...
Twistor form of massive 6D superparticle
(IOP ScienceJournal of Physics A, 2015-12-16)
The massive six-dimensional (6D) superparticle with manifest (n, 0) supersymmetry is shown to have a supertwistor formulation in which its “hidden” (0, n) supersymmetry is also manifest. The mass-shell constraint is replaced ...
Minimal Massive 3D Gravity Unitarity Redux
(IOPClassical and Quantum Gravity, 2015-02-26)
A geometrical analysis of the bulk and anti-de Sitter boundary unitarity conditions
of 3D “Minimal Massive Gravity” (MMG) (which evades the “bulk/boundary clash” of
Topologically Massive Gravity) is used to extend and ...
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 ...
