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…
Universal predictions of Siegel modular invariant theories near the fixed points
Gui-Jun Ding, Ferruccio Feruglio, Xiang-Gan Liu
We analyze a general class of locally supersymmetric, CP and modular invariant models of lepton masses depending on two complex moduli taking values in the vicinity of a fixed poin…
