On polarized scattering equations for superamplitudes of 11D supergravity and ambitwistor superstring
(Springer, 2019-11-14)
We revisited the formalism of 110 polarized scattering equation by Geyer and Mason from the perspective of spinor frame approach and spinor moving frame formulation of the 110 ambitwistor superstring action. In particular, ...
Superstring at the boundary of open supermembrane interacting with D=4 supergravity and matter supermultiplets
(Springer, 2019-12-13)
[EN] We present the complete supersymmetric and κ-symmetric action for the 4-
dimensional interacting system of open supermembrane, dynamical supergravity and 3-
form matter multiplets. The cases of a single 3-form matter ...
Variant 4D supergravities and membranes
(IOP, 2019)
We review the dynamical generation of coupling constants in supergravity by means of gauge three-forms. The latter are introduced as components of particular variant chiral multiplets and can be coupled to membranes ...
