Abstract

The NA62 experiment collected a large sample of charged kaon decays in 2007 with a highly efficient trigger for decays into electrons. A measurement of the 0 electromagnetic transition form factor slope parameter from 1.11 10 6 fully reconstructed K 0 D , 0 D e + e - events is reported. The measured value a = (3.68 0.57) 10 -2 is in good agreement with theoretical expectations and previous measurements, and represents the most precise experimental determination of the slope in the time-like momentum transfer region.
