The CKM matrix from anti-SU(7) unification of GUT families

Understand

We estimate the CKM matrix elements in the recently proposed minimal model, anti-SU(7) GUT for the family unification, $[\,3\,]+2\,[\,2\,]+8\,[\,\bar{1}\,]$+\,(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.
