This operator ( O 1 / 2) can mediate decays of the K meson that change the isospin by 1 / 2 unit, such as K 0 → π + π −, but not processes that change the isospin by 3 / 2, such as K + → π + π 0. I understand that the three pions form a triplet of isospin, while the kaons form two doublets of isospin.
