Description

The preliminary result of the measurement of the vector form factor slope parameter λ+ for the K+ π0e+ν decay is shown. It is based on 14000 events, which account for only 1/4 of all the experimental data selected on processing. The result is in good agreement with the world average value and the accuracy of the measurement is comparable with the accuracy achieved in the best experiments. The experiment was carried out at the 'Hyperon' set-up in IHEP. (author)
