2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/37593We report relevant results from NA48 experiment at CERN SPS. NA48 was proposed in 1990 \cite{proposal} to study direct CP violation in $K^0\toππ$ to a level of accuracy sufficient to resolve the inconclusive status left by the previous measurements performed by NA31 \cite{NA31} and E731 \cite{E731}. In 2002 NA48 published the final result \cite{NA48epsoeps}. Small modification to the experimental setup have allowed NA48 to go forward with an extensive investigation of $K^0$ rare decays and hyperon decays. Some results are already available and reported here together with the final CP violation measurement.3 pages, 1 eps figure, XXIII Physics in collisionHigh Energy Physics - Experimenttext
