title = "Fisrt observation and study of K± → π±π0e+e− decay at the NA48/2 experiment",

abstract = "A sample of almost 2000 K± → π±π0e+e− rare decays with a background contamination below 3% is observed for the first time by the NA48/2 experiment at CERN/SPS. The preliminary branching ratio in the full kinematic region is obtained to be BR(K± → π±π0e+e−) = (4.06 ± 0.17) × 10−6 by analyzing the data set recorded in 3-month NA48/2 run during 2003. The measured value is in agreement with the theoretical prediction within one standard deviation.",
