A Split-Signature Type IIB Background on
Brenno Carlini Vallilo
We construct a maximally supersymmetric Type IIB background in signature on the real ten-manifold underlying complex . The spacetime is diffeomorphic to $T^…
Unfolding the Exotic Supergravity Multiplet
Carlo Iazeolla, Per Sundell, Brenno Carlini Vallilo
We provide an unfolded formulation of linearised 6D exotic supergravity with manifest superconformal symmetry including conformal duality transformations. The construction is based…
D-branes and nonlinear interactions in the pure spinor string
Brenno Carlini Vallilo
We develop a coordinate-independent algebraic description of zero-field boundary conditions for the pure spinor string on in the closed-string channel. The constr…
A note on conserved worldsheet supercharges in heterotic pure spinor superstring
Osvaldo Chandia, Brenno Carlini Vallilo
We study conserved worldsheet charges associated with spacetime supersymmetry in heterotic pure-spinor superstrings on curved ten-dimensional superspace backgrounds. Requiring BRST…
Compactifications of Type II Supergravities in Superspace
Osvaldo Chandia, Brenno Carlini Vallilo
We propose a way to describe compactifications of Type II supergravities with fluxes directly from superspace. The superspace used is the one that arises naturally from the pure sp…
Superspaces for heterotic pure spinor string compactifications
Osvaldo Chandia, Brenno Carlini Vallilo
We study supersymmetry conditions for the heterotic pure superstring preserving and N=1 supersymmetry in four dimensions directly from the curved superspace defined by the Berkovit…
