Search for the dark photon in $\pi^0$ decays
A sample of 1.69 x 10^7 fully reconstructed pi^0 -> gammae^+e^- in the kinematic range m_ee > 10MeV/c^2 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 pi;^0 -> gammaA�...

| description | A sample of 1.69 x 10^7 fully reconstructed pi^0 -> gammae^+e^- in the kinematic range m_ee > 10MeV/c^2 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 pi;^0 -> gammaA', A' -> e^+e. No signal is observed, and preliminary exclusion limits on space of dark photon mass m_A' and mixing parameter ϵ^2 are reported. |
