摘要
This paper reviews recent results form the NA62 and NA48 experiments at CERN. NA62 has searched for the K -> pi nu(nu) over bar with an in-flight decay technique. The analysis of 1.2 . 10(11) decays has found one event compatible with the Standard Model prediction, giving an upper limit for the branching ratio of 1.4 . 10(-9) (95% CL) in the background assumption. Prospects for improvements in the measurement are given. Results on the K-l3 decay form factors from NA48/2 are presented as well as the first observation of the decay K-+/- -> pi(+/-)pi(0)e(+)e(-) and the measurement of its branching ratio from the same experiment.
