An experimental study of the form factor in the decay K$\^{+}\rightarrow\pi^{o}e^{+}\nu$.

The q/sup 2/ variation of the form factor f/sub +/(q/sup 2/) in the decay K/sup +/ to pi /sup o/e/sup +/ nu has been studied using a sample of events detected in the CERN 1.1 m/sup 3/ heavy-liquid bubble chamber. The data are consistent with a linear development f/sub +/(q /sup 2/)=f/sub +/(0)(1+ la...

Sumario:The q/sup 2/ variation of the form factor f/sub +/(q/sup 2/) in the decay K/sup +/ to pi /sup o/e/sup +/ nu has been studied using a sample of events detected in the CERN 1.1 m/sup 3/ heavy-liquid bubble chamber. The data are consistent with a linear development f/sub +/(q /sup 2/)=f/sub +/(0)(1+ lambda /sub +/q/m/sub pi //sup 2/) with lambda /sub +/=0.027+or-0.008. (4 refs).
