Extending Weinberg's EFT: effective scalar-tensor theories up to sixth order
Eugeny Babichev, Sukŗti Bansal, Maria Mylova +1
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
Sukŗti 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,…

Loop Blow-up Inflation
Sukŗti Bansal, Luca Brunelli, Michele Cicoli +2
We present a new model of string inflation driven by a blow-up Kähler modulus of type IIb compactifications with a potential generated by string loops. Slow-roll is naturally reali…
