Higher co-dimension de Sitter branes
Florian Niedermann, Antonio Padilla
We extend the arguments of Maldacena and Núñez to include higher co-dimension brane setups and derive a new no-go theorem. Specifically, we show that under reasonable assumptions…

Stückelberg path to pure de Sitter supergravity
SukÅti Bansal, Silvia Nagy, Antonio Padilla +1
We advance the study of pure de Sitter supergravity by introducing a finite formulation of unimodular supergravity via the super-Stückelberg mechanism. Building on previous works,…

Gauge invariance and generalised regularisation
Antonio Padilla, Robert G. C. Smith
We generalise the regularisation scheme in order to develop a framework for systematically studying regularisation of loops in quantum field theory. This allows us to "solve"…
