Extending Weinberg's EFT: effective scalar-tensor theories up to sixth order
Eugeny Babichev, SukÅti Bansal, Sukŗti Bansal +2
We present a systematic construction of the six-derivative effective scalar-tensor theories, extending the four-derivative framework previously developed by Steven Weinberg. The on…

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,…
