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: The Dune experiment as discussed by the authors is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model.

TL;DR: The beam and detector used for the NA48 experiment, devoted to the measurement of Re(e′/e) and neutral hyperon decays, are described in this paper.

TL;DR: The Deep Underground Neutrino Experiment (DUNE) as discussed by the authors is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model.

TL;DR: NA62 as mentioned in this paper is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays, such as the branching fraction of the K+ → π+ ν bar nu decay, which can bring significant insights into new physics processes when comparison is made with precise theoretical predictions.
