Abstract
We estimate the CKM matrix elements in the recently proposed minimal model, anti-SU(7) GUT for the family unication, [ 3 ] + 2 [ 2 ] + 8 [1 ]+ (singlets). It is shown that the real angles of the right-handed unitary matrix diagonalizing the mass matrix can be determined to t 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, CKM = ; ; or of the unitarity triangle. For the choice of CKM = , the phase is close to a maximal one. ©2015 The Authors.
