Abstract

A sample of 4.687 × 10⁶ fully reconstructed K⁺ → π⁺π⁰ _D, π⁰ _D → γe⁺e^- decay candidates in the kinematic range m_ee > 10 MeV/c² with a negligible background contamination collected by the NA48/2 experiment at CERN in 2003-04 is analysed to search for the dark photon (A') via the decay chain K⁺ → π⁺π⁰, π⁰ → γA', A' → e⁺e^-. No signal is observed, and preliminary exclusion limits on space of dark photon mass m'_A and mixing parameter ϵ² are reported.
