Curvature divergences and gravity decoupling in Calabi--Yau rigid limits
Alberto Castellano, Fernando Marchesano, Lorenzo Paoloni
Four-dimensional supergravity theories become rigid in gravity-decoupling limits. We study this effect for type II string compactifications on general Calabi--Yau m…

Higher-derivative supersymmetric effective field theories
Osmin Lacombe, Lorenzo Paoloni, Francisco G. Pedro
In this paper we study higher-derivative supersymmetric effective field theories focusing on the systematic procedure for the elimination of ghosts from the spectrum. Particular at…

The Moduli Space Curvature and the Weak Gravity Conjecture
Alberto Castellano, Fernando Marchesano, Luca Melotti +1
We unveil a remarkable interplay between rigid field theories (RFTs), charge-to-mass ratios and scalar curvature divergences in the vector multiplet mod…
