A Grand-Unified Nelson-Barr Model
We argue that the Nelson–Barr solution to the Strong CP Problem can be naturally realized in an E$_6$ grand-unified theory. The chiral SM fermions reside in three generations of E$_6$ fundamentals together with heavy vectorlike down quarks, leptons doublets and right-handed neutrinos. CP is imposed...
