Spurious gauge-invariance and in Dimensional Regularization
Pablo Olgoso Ruiz, Luca Vecchi
Dimensional regularization is arguably the most popular and efficient scheme for multi-loop calculations. Yet, when applied to chiral (gauge) theories like the Standard Model and i…

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…

Exploring the Flavor Symmetry Landscape
Alfredo Glioti, Riccardo Rattazzi, Lorenzo Ricci +1
We explore flavor dynamics in the broad scenario of a strongly interacting light Higgs (SILH). Our study focuses on the mechanism of partial fermion compositeness, but is otherwise…
