Eclectic flavour symmetries without flavons
Ferruccio Feruglio, Antonio Marrone
We develop a new framework in which eclectic groups are realised as flavour symmetries without flavons. Focusing on the group , we show that it can be realised as a finite im…
On the decay of a light spinless particle into two photons
Ferruccio Feruglio, Gabriele Levati, Robert Ziegler
We analyze the effective couplings of a light, spinless, gauge-singlet particle to on-shell photons. Starting from the most general theory at the electroweak scale, which allow…
Quark and lepton masses
Ferruccio Feruglio, Saul Ramos-Sanchez
Quarks and leptons, the fundamental building blocks of the subatomic world, manifest in three families - replicas with identical quantum numbers that differ only in their masses. A…
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…
CPon Dark Matter
Ferruccio Feruglio, Robert Ziegler
We study a class of supersymmetric models where the strong CP problem is solved through spontaneous CP violation, carried out by a complex scalar field that determines the Yukawa c…
Solving the strong CP problem without axions
Ferruccio Feruglio, Matteo Parriciatu, Alessandro Strumia +1
We formulate general conditions under which the strong CP problem is solved by spontaneous CP violation. Quark-mass matrix elements are polynomials in the CP-breaking order paramet…
