A grand-unified Nelson–Barr model
Abstract We argue that the Nelson–Barr solution to the Strong CP Problem can be naturally realized in an E$$_6$$ 6 grand-unified theory. The chiral SM fermions reside in three generations of E$$_6$$ 6 fundamentals together with heavy vectorlike down quarks, leptons doublets and right-handed neutrino...
