Abstract

We report here a measurement of form factors of K^±_μ3 decay by the NA48/2 experiment at CERN. Using a sample of 3.4×10⁶ events we provide preliminary form factor values according to various parametrizations. The slope of the scalar form factor is in agreement with other measurements and theory predictions.
