Light EFT Strings and Asymptotic Accelerated Expansion
Veronica Collazuol, Alessandra Grieco, Irene Valenzuela
We study the interplay among towers of particles, EFT strings, and EFT membranes near perturbative infinite-distance limits of four-dimensional theories. We show th…

EFT (String) Tower Building
Alessandra Grieco, Ignacio Ruiz, Irene Valenzuela
We develop a bottom-up framework to reconstruct the asymptotic spectrum of light towers in four-dimensional effective field theories directly from their Kähler pote…

EFT strings and dualities in 4d
Alessandra Grieco, Ignacio Ruiz, Irene Valenzuela
We investigate the global structure of the states becoming light at perturbative limits of 4d string and M-theory compactifications, identifying the different duali…
