摘要：
The NA48/2 experiment reports the first observation of the rare decay K (+/-) -> pi (+/-) pi (0) e (+) e (-), based on about 2000 candidates from 2003 data. The preliminary branching ratio in the full kinematic region is . A sample of 4.687 x 10(6) events collected in 2003/4 is analyzed to search for the dark photon () via the decay chain K (+/-) -> pi (+/-) pi (0), , . No signal is observed, limits in the plane mixing parameter epsilon (2) versus its mass are reported.
