Embedding formalism for -extended AdS superspace in four dimensions
Nowar E. Koning, Sergei M. Kuzenko, Emmanouil S. N. Raptakis
The supertwistor and bi-supertwistor formulations for -extended anti-de Sitter (AdS) superspace in four dimensions, , were derived two year…
Towards superconformal higher-spin theory
Sergei M. Kuzenko, Emmanouil S. N. Raptakis
Three years ago, we proposed free off-shell models for superconformal higher-spin multiplets in arbitrary conformally flat backgrounds, constructed conserved confo…
Covariant quantisation of tensor multiplet models
Sergei M. Kuzenko, Emmanouil S. N. Raptakis
The Batalin-Vilkovisky formalism is applied to quantise the supersymmetric generalisation of the Freedman-Townsend (FT) model, which was proposed by Lindström and Roą
Higher-derivative deformations of the ModMax theory
Sergei M. Kuzenko, Emmanouil S. N. Raptakis
We present higher-derivative deformations of the ModMax theory which preserve both duality symmetry and Weyl invariance. In particular, we single out a class of def…
Aspects of superconformal symmetry
Emmanouil S. N. Raptakis
In this thesis we study classical aspects of superconformal field theory via symmetry principles. Specifically, by employing the powerful setup of conformal superspace, we obtain a…
