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, a new measurement of the ratio of the CP-violating amplitudes for KL → 2π0 and KL → π+π− is reported, which gives a value for the parameter describing direct CP violation: Re ϵ'/ϵ = (2.0 ± 0.7) × 10−3.

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.
