Froggatt-Nielsen ALP
Admir Greljo, Aleks Smolkovič, Alessandro Valenti
The Froggatt-Nielsen (FN) mechanism, a prominent framework for explaining the observed flavor hierarchies, generically predicts the existence of an axion-like particle (ALP). This…

Wormholes in the axiverse, and the species scale
Luca Martucci, Nicolò Risso, Alessandro Valenti +1
We analyze a large class of four-dimensional low-energy realizations of the axiverse satisfying various quantum gravity constraints. We propose a novel upper bound…
