Vector-like quarks at the origin of light quark masses and mixing
Abstract We show how a novel fine-tuning problem present in the Standard Model can be solved through the introduction of a $$Z_6$$ Z 6 flavour symmetry, together with three $$Q = - 1/3$$ Q = - 1 / 3 quarks, three $$Q = 2/3$$ Q = 2 / 3 quarks, as well as a complex singlet scalar. The $$Z_6$$ Z 6 symm...
