Abstract

The SU(3)-symmetry breaking observed in the recently measured ratio RΓ(K*0→K0γ)/ Γ(K*+→K+γ) is discussed in the Shifman-Vainshtein-Zakharov approach to three-point functions. The results are in reasonable agreement with the data and rather stable. In particular, they are essentially insensitive to the different values of quark masses and quark condensates usually considered. © 1985 The American Physical Society.
