TL;DR: In this paper, a sample of 1.69 × 10 7 fully reconstructed π 0 → γ e + e − decay candidates collected by the NA48/2 experiment at CERN in 2003-2004 is analyzed to search for the dark photon (A ′ ) production in the π − 0 → − γ A ′ decay followed by the prompt A − → e + − decay.

TL;DR: In this paper, the authors report the results from a study of the full sample of the NA48/2 experiment at the CERN SPS, where they used two different theoretical formulations to determine the difference between the S-wave scattering lengths in the isospin I = 0 and I = 2 states.
