DOI: 10.1007/jhep01(2019)020
Abstract: A bstractWe use ideas of generalized self-duality conditions to construct real scalar field theories in (1 + 1)-dimensions with exact self dual sectors. The approach is based on a pre-potential U that defines the topological… read more here.

Abstract: We construct five-dimensional non-Lorentzian Lagrangian gauge field theories with an SU(1 , 3) conformal symmetry and 12 (conformal) supersymmetries. Such theories are interesting in their own right but can arise from six-dimensional (1, 0) superconformal… read more here.

Abstract: Braneworld theories are often described as low-energy effective field theories (EFTs) featuring an infinitely thin 3-brane and 4D fields exactly localized on it. We investigate whether an exactly localized braneworld can arise as a limit… read more here.
