Analysis of $K_{S}^{0} \to \pi ^{+}\pi ^{-}e^{+}e^{-}$ decays using data from Run 3 at the LHCb Experiment

This report presents an analysis of $K_{S}^{0} \to \pi ^{+}\pi ^{-}e^{+}e^{-}$ decays using data from Run 3 at the LHCb experiment. The performance of the analysis is evaluated through a comparison between real data and Monte Carlo (MC) simulations and employs an offline selection process as well as an alternative approach using a Boosted Decision Tree (BDT) algorithm. The analysis conducted in this project did not reveal any signal peak.
