Solving the strong CP problem in string-inspired theories with modular invariance
Ferruccio Feruglio, Antonio Marrone, Alessandro Strumia +1
We show that solutions to the strong CP problem based on modular invariance can be extended to incorporate features that appear in string compactifications: quarks with mostly posi…

Baryogenesis from cosmological CP breaking
Mateusz Duch, Alessandro Strumia, Arsenii Titov
We show that baryogenesis can arise from the cosmological evolution of a scalar field that governs CP-violating parameters, such as the Yukawa couplings and the theta terms of the…

Heavy neutral leptons and top quarks in effective field theory
Rebeca Beltrán, Giovanna Cottin, Julian Günther +3
We study the phenomenology of heavy neutral leptons (HNLs) at the LHC in effective field theory, concentrating on operators with top quarks. Depending on the operator choice…
