The CKM matrix from anti-SU(7) unification of GUT families
arXiv:1506.08984 · doi:10.1016/j.physletb.2015.08.040
Abstract
We estimate the CKM matrix elements in the recently proposed minimal model, anti-SU(7) GUT for the family unification, +\,(singlets). It is shown that the real angles of the right-handed unitary matrix diagonalizing the mass matrix can be determined to fit the Particle Data Group data. However, the phase in the right-handed unitary matrix is not constrained very much. We also includes an argument about allocating the Jarlskog phase in the CKM matrix. Phenomenologically, there are three classes of possible parametrizations, $\delq=α,β,$ or of the unitarity triangle. For the choice of $\delq=α$, the phase is close to a maximal one.
