“…However, it is stressed in ref. [108] that large electromagnetic corrections in the ∆I = 3/2 case are possible and that the analysis in this sector is more sensitive to small errors in the analysis due to cancellation of large numbers. Clearly, a better empirical determination of the decays K L → 3π, K L → π + π 0 π − and K + → 3π would lead to a precision test of CHPT in the ∆I = 3/2 sector.…”

“…Kambor et al [108] have further investigated these decay modes. They point out that to order M 2 π /M 2 K one can derive relations which are independent of the weak counterterms K 1 , .…”

“…For K → 2π, 3π, these resonances improve the lowest order results because they allow to include the effects of the strong counterterms [13]. However, since they do not generate the genuine weak parameters, which are numerically important [20,21], a more detailed analysis is called for. In particular, the effects of other resonances and the scale dependence of the loops must be investigated and compared with the results of the factorization hypothesis.…”

“…The one-loop analyses of K → 2π [1,3,4,29] show in fact that pion loop diagrams provide an important enhancement of the A 0 amplitude, implying a sizeable reduction (∼ 30%) of the fitted |g 8 | value. This chiral loop correction destroys the accidental numerical cancellation in eq.…”
