Description
It is shown that calculability of the mixing angles in a class of n-generation left-right-symmetric SU(2)/sub L/ x SU(2)/sub R/ x U(1) models restricts the fermion mass matrix to be of the form Σ/sub m/=0 /sup n/ direct-sum I/sub m/A/sub m/ with the constraint Σ/sub m/=0 /sup n/mI/sub m/=n, where A/sub m/ is a nonsingular m x m Hermitian or complex symmetric block containing 2m-1 elements and I/sub m/ is the number of such blocks. Such a mass of matrix cannot supply CP-invariance-violating phases
