文摘The influence of the isospin-breakingπ^(0)-η-η′mixing effect on the CP-asymmetries of B→Kπprocesses is examined for the first time.It is found that this mixing effect presents significant uncertainty for both the CP-asymmetry sum rule of B→Kπprocesses and the CP-asymmetry difference of B+→K+π^(0)and B0→K+π-,potentially obscuring the significance of the Kπ-puzzle.As the correction caused by theπ^(0)-η-η′mixing effect is highly dependent on four strong non-perturbative phases,a definitive conclusion is currently unavailable.
