Résumé

A preliminary result of a new measurement of the K+ ?p+µ+µ- form factor parameters and branching fraction using the NA62 Run 1 data set collected in the years 2016 - 2018 is presented. From the observed sample of 28011 K+ ? p+µ+µ- event candidates with negligible background contamination, the form factor parameters a+ = -0.592 ± 0.013stat ± 0.007syst ± 0.001ext and b+ = -0.699 ± 0.046stat ± 0.035syst ± 0.003ext, and the branching fraction B(K+ ? p+µ+µ-) = (9.27 ± 0.07stat ± 0.08syst ± 0.04ext) × 10-8 are obtained.
