Integral Scaling for EFT Strings from the Bottom-Up

Muldrow Etheredge, Alvaro HerrÃ¡ez, Dieter LÃ¼st +1

Near the core of an EFT string in a 4d $N = 1$ theory, the scalars are dynamically driven to infinite field distance and a tower of states becomes light, with mass scaling…

Curvature divergences in 5d $N = 1$ supergravity

Alejandro Blanco, Fernando Marchesano, Luca Melotti

We study the scalar curvature $R$ of the vector moduli space of 5d $N = 1$ supergravities, obtained by compactifying M-theory on a Calabi--Yau three-fold. We find that $R$ …

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 $I^^{3}$ and scalar curvature divergences $R_{div}$ in the vector multiplet mod…
