Quark Mixing in Chiral SU_n×SU_n Broken Symmetry in the Limit of Exact SU_k×SU_k Symmetry

摘要

The structure of chiral SU_n×SU_n symmetry breaking in the limit of exact chiral SU_k×SU_k symmetry (k < n) is considered. The mixing angle is determined by the masses and decay constants of pseudoscalar mesons.
