Summary
Solving four sets of relations involving the Kt3 form factorsF ±(q 2) and the ratioF K/F π obtained in a previous paper, the values ofF +(0) andF K/F π are found to be functions of the symmetry-breaking parameterb=〈0‖S 8(0)‖0〉/〈0‖S 0(0)‖0〉. Near a value ofb=−0.22, which is close to the one estimated by Mathuret al., we find that the form factorF +(0) is almost nonrenormalizable andF K/F π≃1.28.
Riassunto
Risolvendo quattro sistemi di relazioni interessanti i fattori di forma di Kt3,F ±(q 2) ed il rapportoF K/F π ottenuto in un articolo precedente, si trova che i valori diF +(0) edF K/F π sono funzioni del parametro di rottura della simmetriab=〈0‖S 8(0)‖0〉/〈0‖S 0(0)‖0〉. Per un valore dib prossimo a −0.22 e molto vicino a quello calcolato da Mathuret al., si trova che il fattore di formaF 1(0) è quasi non rinormalizzabile e cheF K/F π≃1.28.
Резюме
Решая четыре системы соотношений, включающих Kt3 формфакторыF ±(q 2) и отношениеF K/F π, полученное в предыдущей статье, обнаружено, что величиныF +(0) иF K/F π являются теперь функциями параметра нарушения симметрииb=〈0‖S 8(0)‖0〉/〈0‖S 0(0)‖0〉. Вблизи значенияb=−0.22, которое близко к значению, полученному Матуром и др., мы находим, что форм-факторF +(0) является почти непенормируемым иF K/F п∼1.28.
