Recent NA48/2 and NA62 results Conference Paper uri icon

abstract

  • The NA48/2 Collaboration at CERN has accumulated and analysed unprecedented statistics of rare kaon decays in the Ke4 modes: Ke4(%2b-) (K± p%2bp-e±) and Ke4(00) (K± p0p0e±) with nearly one percent background contamination. It leads to the improved measurement of branching fractions and detailed form factor studies. New final results from the analysis of 381 K± p± rare decay candidates collected by the NA48/2 and NA62 experiments at CERN are presented. The results include a decay rate measurement and fits to Chiral Perturbation Theory (ChPT) description. © Published by ARISF, 2014.
