Leptonic CP violating Phase in the Yukawaon Model

Koide, Yoshio · Nishiura, Hiroyuki

Original · EN

In the so-called "Yukawaon" model, the (effective) Yukawa coupling constants Yfeff are given by vacuum expectation values (VEVs) of scalars Yf (Yukawaons) with 3× 3 components. In this brief report, we change VEV forms <Yf> in the previous paper into a unified form. Therefore, parameter fitting for quark and lepton masses and mixings is revised. Especially, we obtain predicted values of neutrino mixing ² 2θ₁₃ and a leptonic CP violating phase δCPℓ which are consistent with the observed curve in the (² 2θ₁₃, δCPℓ) reported by T2K group recently.
