Abstract

In the spirit of Non-commutative differential calculus on discrete group, we construct a toy model of spontaneous CP violation (SCPV). Our model is different from the well-known Weinberg-Branco model although it involves three Higgs doublets and preserve neutral flavor current conservation (NFC) after using the Z2 Z2 Z2 discrete symmetry and imposing some constraints on Yukawa couplings.
